Google’s Gmail email service will strengthen security measures. They will act on user attempts to access sensitive settings, writes Ars Technica.

These are settings such as account forwarding, editing filters, or changes to the IMAP protocol. In this case, the user must go through two-factor authentication (2FA), even if they are already logged in.

If the authentication fails or is not answered, the user will see a bright red pop-up window with the words “Critical security alert”.

The company is taking such measures to stop attackers from compromising someone else’s account. The rollout of this feature has already begun.

By the way, in the spring, Gmail decided to add a blue checkmark to emails to improve sender verification.
