Two-factor authentication is a security measure that requires users to provide two forms of identification in order to access a computer system or network. This adds an extra layer of security beyond just a password.
The first factor is typically something the user knows, such as a password or PIN. The second factor is something the user has, such as a physical token or mobile device. When logging in, the user must provide both factors in order to gain access.
For example, when logging into an online banking account with two-factor authentication enabled, the user may be required to enter their password and then also enter a code that is sent to their mobile phone via text message.
Two-factor authentication can help protect against unauthorized access and identity theft. It is recommended that users enable two-factor authentication whenever possible for sensitive accounts such as online banking or email.
Many online services and applications offer two-factor authentication as an option. Check with your service provider for instructions on how to enable it for your account
