Google he said that simplifies the 2-step verification process (2SV from 2-Step Verification) for user accounts. You can now activate 2SV without adding a phone number.
Before the change, Google required users to provide a phone number before you could set up 2SV. Now, from your account settings, you can skip the phone number if you want to use another method.
The article published by Google highlights the fact that this change will help administrators enforce 2SV policies in their organizations. But the move is welcome by all users.
Google lets you choose between 3 options for setting up a 2-step verification. You can choose to use one application control ID cardlike Google Authenticator or Microsoft Authenticator. I would suggest looking into open source alternatives like Aegis Authenticator for Android or 2FAS (Android, iOS).
Optionally, you can use a hardware security key, such as a YubiKey.
The best part is that the new verification process is not exclusive to Google Workspace customers. It is available for all users, including personal accounts. The announcement states that the change will be implemented over the next two days. If you haven't already done so, you can enable 2-step verification for your Google Account from your account security page.
