Why do I have to wait 48 hours to reset Google password?
This is a delay between when a request to recover your account is made and when the account recovery claim is processed. If there's something unusual about your recovery request, this delay helps protect your account.
Why can't I recover my Gmail?
To protect your account, we limit the number of times you can attempt password recovery via email, SMS, or Account Recovery form. Google temporarily disables a particular account recovery option after too many incorrect attempts. The recovery option will be re-enabled on the date indicated below that recovery option.
