Gmail Security: Turn on 2-Step Verification
Two-step verification, also known as 2FA or two-factor authentication, is a security process in which a user provides two different authentication factors to verify their identity. The first factor is typically a password or PIN, while the second factor is usually something the user has, such as a mobile device or security key .
2FA adds an extra layer of security to your account and helps protect it from unauthorized access. If someone tries to log in to your account from an unknown device, they will need to provide the second factor in addition to your password. This makes it much more difficult for hackers to gain access to your account .
