I am trying to add an alternate email address to my Gmail account but I cannot because Google says it's already in use. I can't find where it's in use and have been researching this for days. Any suggestions, help, or answers is greatly appreciated.

  • Please add the textual error message. Also add a brief description of your search efforts as is suggested in How to Ask.

  • When I try to add the email to alternate emails "This email is already in use with a Google account". Oct 10, 2021 at 14:49
  • Try recover the password of the account using your intended email address. Ref. webapps.stackexchange.com/q/52706/88163. If you need further help, please edit the question to add more details.

I spent too much time trying to crack this and finally figured out a solution. This applies if you're in a very specific situation where all of these apply:

  • When you try to add an alternate email to your account, you get a message that "This address is already used with a google account".
  • When you enter your alternate email in the Google sign-in and choose "Forgot Password", it says "Couldn’t find your Google account".
  • You can't find any recent Google Docs where you were editing or commenting as an anonymous account. If these exist, it's possible this process might lose these edits, I'm not certain.

There are a number of questions on Google's support site from people in this predicament, most of them with very unhelpful answers. The best one contains the nugget of information that when you accept an invitation to edit that was sent to your alternate email, Google creates a "visitor session" and the existence of this visitor session can block you from adding it to your existing account. Unfortunately, Google's official support docs seem to be out of date and refer to UI elements that aren't there.

After much trial and error, I found a path to get rid of this visitor session so you can add your alternate email.

  1. Log in to your Google account.
  2. Find or create a Google Docs document that you own. Doesn't matter what the contents of the document are. Click Share and share it with your alternate email address, allowing editing.
  3. Either sign out of your Google account or open an incognito window. When the email arrives to your alternate address, open the link in the email (if you're using an incognito window, copy the link and paste it into the incognito session so it doesn't open in your regular window).
  4. You should now see the document with a button on the top right that says Sign Up To Edit (not the button to sign in). Click this button.
  5. You will see a form to create a new account. Enter your alternate email address and a password. You won't finish creating the account so the password doesn't really matter, but enter something you'll remember just in case anything goes wrong.
  6. When you submit this form, you should see a warning that you have an existing visitor session. Confirm that you wish to delete the visitor session.
  7. Don't continue with the sign-up process! Instead, return to your Google account and add your alternate email through there. You should now be able to do so successfully.
  • You're an absolute lifesaver! What a convoluted solution. Can't believe there's not a method of remediation directly from the "add alternate email" form/page.

  • Glad I could help! I knew I couldn't be the only person hitting this wall. Took me literal months to figure it out, so I'm glad I could save you some trouble. And yes, this is just extremely poor engineering and UI on Google's part. Feb 17 at 20:11
  • I soooo owe you one!!

Two Approaches

1. Password Reset

This is a good method however any devices, applications, or services logged in using your Google password will need to have the password updated in order for them to regain access.

There are variations on this, but to reduce the number of instructions I am providing only one success path:

  1. From your computer's web browser, sign in to Google: Google Sign In Link
  2. On the top right corner of the webpage select your profile image or initial(s). I am referring to the one directly opposite the 'Google Account' logo not one that may be in your browser's toolbar(s):
    enter image description here
  3. On the menu, choose Add another account.
  4. Enter your 'alternate email address' in the field 'Email or phone' and click 'Next'.
  5. Instead of entering a password, select the 'Forgot password?' link located to the left of the 'Next' button see image.
  6. As part of the password reset process you will learn what Google account is tied to the 'alternate email address'.
  7. Update any affected devices with the newly created Google password.

2a. Clues in 'alternate email address' Mailbox

You can search for email messages in the 3rd party mailbox belonging to the 'alternate email address'.

  1. The alternate email address could not have been added to a Google account in the first place unless it could be proven (as part of the setup) that the person adding it has control/access over that address.
  2. Google may also have sent emails flagging 'important security-related information about your account' when you logged in through a new location, app, etc.
  3. Google may have sent other emails related to policies, Play Store transactions, or even marketing.

Ways to Search

    to: your alternate email address
    from: no-reply@accounts.google.com

    keywords:  "Verify your added email"
          or:  "This is a copy of a security alert sent to"
          or:  "Security alert for your linked Google Account"
          or:  "New sign-in to your linked account"
          or:  "New device signed in to"

2b. Clues in your Gmail Accounts

If you have a small number of Gmail accounts, you could search in each one for text strings that are found in the verification email that you would have received.

Current sample of the verification email:

from: Google no-reply@accounts.google.com
to: [you@yourdomain.com]
date: Oct 17, 2021, 6:27 PM
subject: Security alert
message: A request was made to add ['alternate email address'] to your Google Account. Click here to verify this request. This email comes as a surprise? Please ignore this mail and don't click on the link above. Someone might have just mistyped their email address and accidentally tried to add yours. In this case your email address will not be added to the other account.

You can also see security activity at https://myaccount.google.com/notifications

You received this email to let you know about important changes to your Google Account and services.

Good Luck!


@Ian Greenleaf, this worked! Thank you. I just spent 2 hours on Google's Chat going in circles. This is exactly what happened. I wish I could post it on this discussion too:

"This address is already being used with a Google Account" https://support.google.com/accounts/thread/55497010/this-address-is-already-being-used-with-a-google-account?hl=en


@Ian Greenleaf Young: your solution got me on the right track.

I found that a collaborator of mine had shared a google doc with me using the account that I now could no longer add to my gmail account. Your exact solution didn't work for me, but what did work was to search my email for the phrase "Delete visitor session" in an invitation to edit a google doc. Clicking that link allowed me to indeed delete the visitor session and free up the account to be linked to my google account!
