Why Does My Gmail Automatically Sign Out? Here’s How I Fixed It [2025 Guide]
I’ve noticed that Gmail sometimes automatically signs me out, which is annoying. It’s happened to me when I was checking important emails or replying to work messages. I figured out the most common causes why does my Gmail automatically sign out, and how to fix them.
In this guide, I’ll explain exactly why Gmail might be signing you out and the steps I used to stop it.
Why Does My Gmail Automatically Sign Out?
Here are the key reasons why the automatically sign out Gmail issue occurred:
#Reason 1. Multiple Google Accounts
I use multiple Google accounts on the same browser. If you do the same, you might notice Gmail logging you out unexpectedly. This usually happens because of session conflicts between accounts.
To resolve this, I now use different browser profiles for personal and work accounts. It keeps avoiding sign-out issues.
#Reason 2. Browser Cookies Being Cleared
Cookies store session information. If your browser is set to clear cookies automatically when you close it, Gmail will sign you out every time.
To fix this, I stopped this setting using these steps:
- Open the browser’s settings (if Chrome browser: Settings > Privacy & security > Cookies and other site data).
- Then turn off Clear cookies and site data.
- I also added [mail.google.com] to the ‘Sites that can always use cookies’ list.
#Reason 3. Outdated or Corrupted Browser Cache
An outdated or corrupted cache can sometimes cause login issues with Gmail. I remember Gmail kept signing me out even though I didn’t log out manually.
Clearing the cache fixed this for me. In Chrome, it’s: Settings > Privacy and Security > Clear browsing data > Cached images and files.
#Reason 4. Google Account Security Check
Sometimes, Gmail signs me out because of suspicious activity or if I log into my account from a new device or location. Once I accessed Gmail from a hotel Wi-Fi, and Google detected unusual activity, it automatically signed me out.
To address why does my Gmail automatically sign out, I completed the Google Security Checkup and updated my password just to be safe.
#Reason 5. Third-Party Extensions or Apps
Some browser extensions or third-party apps can interfere with Gmail sessions. After disabling it, the auto sign-out issue will stop.
#Reason 6. Device-Level Sign-Outs (Android/iOS)
On my Android phone, I noticed Gmail kept logging me out because of changes in device security settings, like when I reset my phone’s password or enabled two-factor authentication.
To fix why does my Gmail automatically sign out, I ensured that Google Play Services and the Gmail app were updated. Also, I checked that auto-sync was turned on.
#Reason 7. Two-Factor Authentication (2FA) or Password Changes
Whenever I change my Google password or enable 2FA, Gmail signs me out of all sessions.
For the same, after enabling 2FA, I keep backup codes saved securely in case I need to sign in again quickly.
#Reason 8. Gmail Account Session Expired
Sometimes Gmail simply signs me out if I’ve been inactive for a long time, or due to session expiration policies by Google.

Keep Your Gmail Emails Safe
While fixing the reasons behind Gmail automatically signing me out, it also got me thinking: what if I lost access to my Gmail completely? I think no one wants to lose their crucial data for any reason.
That’s why I now use an SysTools IMAP Backup Tool to regularly back up my Gmail emails. It automatically downloads a complete copy of my emails to a local system.
This solution can backup data in several file formats, including PST, PDF, MBOX, EML, TXT, MSG, CSV, HTML, and MHT. You can import these file formats in multiple email services like Outlook(PST), Thunderbird(MBOX), and others.
So, don’t rely on one service for data storage, as it is risky too; taking an offline backup of data is always a better option.
