How can I find out which Gmail accounts have my cell phone attached to them? I created accounts and now need to delete any that have cell number attached to them.
Here is what I would do:
Sign out of account #1.
Go to the Forgot Password link for Account #1
Select I don't know a previous password
On the page that says password help for •••••••@gmail.com, if there is a Get a verification code on my phone: •••••••### option then your phone is associated with the account. If not, the cell number is not associated.
Repeat for as many accounts as needed.
