How i check any other emails who list my Gmail account as their recovery email?

 for the username :   click here   enter the recovery address or phone number  , but you need to know the name/s of those accounts ( not the addresses - the name/s )   - a list of any usernames associated with that recovery email address will be sent to the address you provided , or shown on screen , or sent to your phone  ,   or :   ask a friend who you emailed from that address , or locate your original email from gmail when you created that address by searching for subject:"has been created"   , or check your browser  history maybe you used it to log into another site , or check your browser's auto fill options - it may be there   . no other way im afraid
