Google Workspace We detected an unusual sign-in attempt

Google workspace formerly g-suite

There’s nothing more frustrating than trying to manage a former employee’s email and after changing their password in Google Workplace Admin receiving the dreaded message of protection. Otherwise known as the ‘Login Challenge’.

We detected an unusual sign-in attempt. To make sure that someone else isn’t trying to access your account, your organization needs you to sign in using your corporate mobile device (the phone or tablet you normally use to access your corporate account).

If you don’t have your corporate mobile device with you right now, try again later when you have your corporate mobile device with you. If you continue to have problems signing in, contact your administrator.

Google provides some links that get you absolutely nowhere. So I’m here to spare you the trouble.

Don’t bother suspending and unsuspending your former employee’s account, it will not get you anywhere, despite some claims to the contrary. While in the past it might have ‘broken the link’ this seems to no longer be relevant.

Instead, you need to use the somewhat dubious security control of ‘disabling the login challenge’. Which will “Turn off identity questions for 10 minutes after a suspicious attempt to sign in.”

As far as I can tell this workaround should time out after 10 minutes but Google does not provide a handy countdown or any identifiable way of telling if the login challenge has been reactivated.

Provided you are not leaving an administrator account vulnerable, I say go ahead it is worth the risk.

How to disable the Login Challenge:

  1. Login to Google Admin
  2. Navigate to the specific user via:
    1.  Directory… Users… Specific User
    2.  Search for the user in the top search bar
  3. Once in the User’s Profile, scroll down and select Security
  4. Scroll and select ‘Login Challenge’
  5. Select ‘TURN OFF FOR 10 MINS

  1. This workaround doesn’t seem to be successful anymore.. There’s no more ‘Security’ option next to the User’s profile.. Do you know of another way?

    • I can still see the Security section in my Google Workspace Business Standard admin. I’ll see if I can add a screenshot of the section. It’s in the main window below User information.

      Are you sure you are using Google Workspace?

  2. Thank you so much for this post Paul! I could not figure out how to get around this stupid message!

    You are awesome!

  3. Seems to work as of 2023, tested and working by accessing the user account after another user requested to reset password. It only works for 10 minutes though.

  4. So what do you do when you disable the Login Challenge, and it still only lets you send a G-XXXXX code to the users phone? This sucks for former employees, because they WON’T give you the code. Stupid Google.

    • That means you’ve switched on 2-step verification. It is probably on for the entire Google Workspace Account. Good news is you can turn it off for that ex-eployees account.

      Admin > Users > User Name > Security > 2-step verification
