I can't sign in to my email client?
If you can't sign in to your email client, you might see one of these errors:
- "Username and password not accepted"
- "Invalid credentials"
- You're asked to enter your username and password over and over
Step 1: Check your passwordIf you have these problems or can’t sign in, first check to make sure you’re using the right password.
Step 2: Try these troubleshooting steps
- Update your email client to the latest version.
- Use an App Password: If you use 2-Step Verification, try signing in with an App Password.
- Allow less secure apps: If you don't use 2-Step Verification, you might need to allow less secure apps to access your account.
- If you recently changed your Gmail password, you might need to re-enter your Gmail account information or completely repeat your Gmail account setup on your other email client.
- If the tips above didn't help, visit https://www.google.com/accounts/DisplayUnlockCaptcha and follow the steps on the page.
- The email client's sign-in method might be insecure. Try signing in directly on the Gmail app.
- Make sure your mail app isn't set to check for new email too frequently. If your mail app checks for new messages more than once every 10 minutes, the app’s access to your account could be blocked.
"Too many simultaneous connections" error
You can only use 15 IMAP connections per account. If you have many email clients getting messages from Gmail at the same time, you may see the "Too many simultaneous connections" error.
If you use multiple email clients or devices for the same Gmail account, try closing or signing out of some.
Security certificate CN error
Try the options below if you see this error: "The server you are connected to is using a security certificate that could not be verified. The certificate's CN name does not match the passed value."
- Make sure you've set up your mail client for IMAP and not POP.
- Check your Incoming Server setting to make sure it says

You might be downloading too many emails at one time.
To fix this:
- Update your IMAP settings so you don't sync certain folders.
- Remove your Gmail account from your email client, then try adding it again.
- In your Gmail IMAP settings, set IMAP to only sync folders with 10,000 emails or fewer.
