Google Ads does not expose a raw login log, but the Change History report gives you a timestamped, per-user record of every modification made inside the account — going back up to 24 months. For a rough "last seen" indicator at the user level, the Access & Security panel shows when each user was last active. Together, these two tools let you hold account managers accountable without needing server-level audit logs.
Key takeaways
Change History is your primary accountability tool: it logs every change by date, time, and the email address of the user who made it.
Change History shows changes, not logins — a manager who reviewed the account but made no edits will leave no trace in the report.
The Access & Security panel shows all users, their permission level, and a "last active" indicator, which is the closest native approximation to a login timestamp.
Automated changes from Smart Bidding or automated rules appear in Change History under their own labels, so always filter by the human user's email to assess real management activity.
Account ownership matters as much as access monitoring — your business should hold Admin credentials, with agencies granted Standard access or linked via MCC.
Key terms
Change History
A native Google Ads report that logs every modification made to the account, including the date, time, and email address of the user who made each change, going back up to 24 months.
MCC (My Client Center)
A Google Ads manager account that allows an agency or individual to access and manage multiple client accounts from a single login without being listed as a direct user on each account.
Access & Security
The Google Ads settings panel that lists all users with access to an account, their permission level, and a last-active indicator.
Smart Bidding
Google's automated bid strategy system that uses machine learning to adjust bids at auction time; its automated changes appear in Change History under system labels rather than a human user's email.
Admin access
The highest Google Ads permission level, granting full control over campaigns, billing, and user management — including the ability to add or remove other users.

What does Google Ads actually log when someone accesses the account?
Google Ads does not maintain a traditional login timestamp log the way a web server or CRM might. What it does maintain is a comprehensive change log — a record of every action taken on campaigns, bids, budgets, ads, extensions, audiences, and account settings. [1] This distinction matters: visibility into what changed is often more useful than knowing someone clicked a login button, because it tells you whether the account is actually being worked on.
This question comes up regularly in the PPC community — the original thread on r/PPC is a good example of how often advertisers and business owners wrestle with it, usually because they're paying for active management and want to verify that work is happening.
Key Insight: A change log is frequently more valuable than a login log. A manager who logs in and does nothing is a bigger problem than one whose access pattern looks unusual. The Change History tells you whether decisions are actually being made.

How do you use the Change History report to track account activity?
The Change History report is the most direct way to see who did what and when inside your Google Ads account. [1] Access it by following these steps:
Log into ads.google.com.
In the left-hand navigation, scroll to Change history (near the bottom of the campaign tree).
Set your desired date range — you can look back up to 24 months.
Use the User dropdown filter to isolate activity by a specific email address.
Export the results as a CSV for offline analysis or to share with stakeholders.
Each row in the report shows the date and time of the change, the email of the user who made it, what object was changed (campaign, ad group, keyword, bid, budget, etc.), and the before and after values.
Best Practice: Filter Change History by your account manager's email address for the last 30, 60, or 90 days and export to CSV. A simple row count gives you a baseline. In accounts I manage at meaningful spend levels (>$5,000/month), a healthy account manager should be generating 50–150+ logged change events per month across bid adjustments, audience refinements, ad copy tests, negative keyword additions, and budget reallocations. On smaller accounts (<$5,000/month), 15–40 meaningful human-initiated changes per month is a reasonable expectation. Single-digit totals on an active account are a red flag.
What Change History does not show
The critical limitation: Change History only records changes. If a manager logged in, reviewed the account, concluded nothing needed to be adjusted, and logged out, that visit produces zero entries. A quiet period in the log could mean disciplined, strategic management — or it could mean the account was ignored. You need context alongside the data.
Common Mistake: Assuming a busy Change History means good management. Automated rules, Smart Bidding adjustments, and bulk machine-triggered changes can inflate the activity log significantly. Always filter by the specific user's email to distinguish human-initiated changes from automated system actions.

Where can you see who has access to the account right now?
The Access & Security panel gives you a live view of every user with access, their permission level, and a "last active" indicator — the closest native equivalent to a login timestamp at the user level.
To get there: Tools & Settings (wrench icon) → Setup → Access and security.
Google Ads access levels explained
Access Level
What They Can Do
Best For
Admin
Full access: billing, user management, all campaign operations
Internal stakeholders or primary owner only
Standard
Create, edit, and manage campaigns; view all reports; cannot manage users or billing
Account managers, day-to-day operators, agencies
Read-only
View campaigns and reports; cannot make changes
Clients, stakeholders, junior reviewers
Email-only
Receives automated email reports; no dashboard access
Executive reporting recipients
Best Practice: Audit Access & Security quarterly. It is surprisingly common to find former employees, ex-agencies, or one-off contractors who still have active Admin access months or years after the relationship ended. Every ghost user with Admin credentials is a live security liability. Use the 250-point Google Ads audit engine to surface access issues alongside campaign-level problems in one pass.

How does MCC (agency manager account) access change the picture?
If your account is linked to an agency's MCC (My Client Center), the access audit becomes more complex because individual team members at the agency may manage your account from the MCC level without ever appearing in your account's own user list.
What you can see in an MCC relationship
Change History still logs email addresses of the specific person making changes, even if they access through MCC — this is your best window into agency-side activity.
You can see which MCC is linked under Tools & Settings → Account Settings → Manager accounts.
You cannot see the full roster of who within the agency has MCC-level access unless they have also been directly invited to your account.
How to protect yourself in agency relationships
The single most important structural decision is account ownership. Your Google Ads account should be created under your business's Google login, with you as Admin. The agency receives Standard access or is linked via MCC — never the reverse. If an agency sets up the account under their own login, you do not own it, and recovering that account if the relationship ends can be extremely difficult. For a deeper look at what Google Ads does and doesn't log at the account level, including MCC nuances, that resource covers the topic in detail.
Key Insight: In MCC-managed accounts, the Change History email column is your most reliable source of truth about who at the agency is actually touching your campaigns. Request a filtered Change History export as part of every monthly agency deliverable.

How do you build an ongoing monitoring system instead of one-off audits?
Periodic manual checks are better than nothing, but a lightweight proactive system removes the need to remember to look.
Automated performance alerts
Google Ads has a built-in rule system that can email you when key metrics deviate:
Go to Tools & Settings → Bulk Actions → Rules.
Create a rule that triggers when daily spend drops to $0 on an active campaign (a reliable signal that campaigns have been paused unexpectedly).
Create a second rule for significant week-over-week drops in conversions or conversion rate. [2]
Set notification frequency to daily for critical spend-level metrics.
These alerts don't tell you who logged in, but they tell you when the account starts behaving like no one is home — which is the outcome you actually need to prevent.
Looker Studio dashboards with scheduled Change History exports
For more robust monitoring, connect Google Ads to Looker Studio (formerly Data Studio) and use the Google Ads API or scheduled Google Ads scripts to export Change History data into Google Sheets on a recurring basis. This creates a live, visible audit trail without manual exports each month. If you want a faster path to visibility, the marketing analytics auditor can surface account health signals including activity gaps.
Common Mistake: Relying solely on performance metrics to judge whether your account manager is doing their job. CPC, CTR, and ROAS fluctuate for many reasons outside a manager's control — seasonality, competitor behavior, algorithm changes, creative fatigue. Performance data tells you outcomes; Change History tells you activity. You need both for an accurate picture. See also what active paid search management looks like after initial setup for a frame of reference on what ongoing work should actually produce.

How do you have the accountability conversation if the data looks concerning?
If Change History data raises questions, lead with specific data rather than accusations. A good account manager will be able to explain every decision — and will also be able to point out legitimate management work that doesn't generate change events: keyword research, competitive analysis, audience building in Google Analytics 4, landing page review, and bid strategy evaluation.
Useful openers:
"I pulled Change History for the last 60 days and see [X] changes attributed to your email — can you walk me through what you worked on during this period?"
"There's a three-week stretch in [month] with no logged changes. What was happening with the account during that time?"
"Can we agree on a monthly reporting format that includes a Change History export going forward?"
If a manager gets defensive, refuses to discuss the data, or cannot explain a prolonged period of zero activity on a spending account, that response is itself significant information about the relationship. You can use Buddy, the AI Google Ads agent, to run an independent account review if you want a second perspective before that conversation.

What to do next
Run Change History now. Set the date range to the last 90 days, filter by each user's email, export to CSV, and count human-initiated change events by user. Baseline what active management looks like in your account.
Audit Access & Security. Remove any users who no longer work on the account. Downgrade any Admin users who don't need Admin-level access to Standard.
Verify account ownership. Confirm your business email is the primary Admin. If an agency or former contractor holds that role, reclaiming it should be your immediate priority.
Set up performance alert rules. At minimum, create an alert for spend dropping to $0 on active campaigns and another for significant week-over-week conversion drops.
Make Change History a standard monthly deliverable. Whether managing internally or through an agency, a filtered Change History export should be a normal part of reporting — not an adversarial one-off audit. Explore the full tracking & measurement resource library to build the rest of your measurement infrastructure around it.

Frequently asked questions
Can I see the exact time someone logged into my Google Ads account?
No. Google Ads does not provide a login timestamp log. The closest available data is the "last active" indicator in the Access & Security panel, which shows approximate recent activity for each user, and the Change History report, which timestamps every change a user makes. If a user logs in but makes no changes, neither tool will record the visit.
How far back does Change History go in Google Ads?
The Change History report retains data for up to 24 months. You can set a custom date range within that window and filter by user email, campaign, or change type. For accountability purposes, a 90-day rolling export is a practical starting point for most account reviews.
Will Smart Bidding changes show up in Change History and inflate the activity count?
Yes. Automated bid adjustments made by Smart Bidding strategies, automated rules, and accepted optimization suggestions all appear in Change History — often under a system label rather than a human email. This is why filtering the report by a specific user's email address is essential before drawing conclusions about how actively a human manager is working the account.
If my agency manages my account through their MCC, do their team members appear in my Change History?
Yes — the email address of the individual who made a specific change will appear in Change History even when access is through an MCC. However, the Access & Security user list in your account will only show users directly invited to your account; it will not list all employees at the agency who have MCC-level access. The Change History email column is therefore more informative than the user list for tracking agency activity.
What should I do if an agency or former employee still has Admin access to my account?
Remove or downgrade their access immediately via Tools & Settings → Access and Security. If the former user is the account Admin and you are not, contact Google Ads support to initiate account recovery. Going forward, ensure your business holds the Admin role and that all external parties receive only Standard or Read-only access as appropriate to their role.
Is there a third-party tool that provides better access logging than native Google Ads?
No third-party tool can access Google's internal authentication logs, so none can show true login events. Tools like Optmyzr and Adalysis can supplement the native Change History with account health scoring and optimization tracking, but for raw accountability on who changed what and when, the native Change History report accessed directly in Google Ads — or via the Google Ads API — remains the authoritative source.
