A group project I am involved in has a shared Gmail account for a while now. There is no single number associated with this account which I am aware of.

I was trying to log from another device than a usual one so Google asked me to prove I am human. Hence a SMS or phone call option ...Authenticating a user via SMS. This is not a two factor authentication.

Once in I was looking for a trace of my phone number so as to delete it. Where would Google store it with in the shared account if it does store it.

Any thoughts?

    If it was a "prove you're human" step, then they probably don't have the number stored at all. Presumably a bot isn't going to be able to act on an SMS message. If it's a "prove you're you" step, then something else is going on.

... if it does store it

Presumably you did not have to enter your phone number during this authentication stage? So, it must already have been "stored"?

Or, if this was literally just a "prove you're human" step and you were required to enter your phone number, then I doubt that Google would store this phone number with the account. (?) Although I have not experienced this type of "prove you're human" validation. The usual Google anti-bot check these days is a "simple" checkbox (formerly a captcha).

To check your account:

  1. Navigate to your Google Account:

  2. Your personal info - check the phone number

You should also check the "Security alerts settings", as this will show the phone number (entered above) and whether this is enabled:
