I haven’t opened the email, I’m just looking at the preview that gmail provides and it contains the name of my email with the first character missing and most of my phone number, like I stated in the title of my post. How concerned, if at all, should I be and is there anything I should be doing?
Use a 2FA app, not SMS. SIM swaps are easy to do to take over your accounts and change your passwords. An app on your phone renders this useless.
