As you may already know, Google accounts recommended password recovery options are ‘Recovery email address’ and ‘Recovery mobile phone number’. These recovery options help users to reset their password by having an email sent to their recovery email address, or by having a text message sent to their recovery mobile phone number.
According to Google,
Users without recovery options are 9 times more likely to lose access to their accounts. Losing access can mean not being able to send mail to friends, not being able to access photos or documents you’ve created online, and not being able to access any of the information stored on your Google Account.
So, to make sure you protect your account and don’t lose any of your important info it’s always a best practice to keep your password recovery options up-to-date.
