2 factor authentication is an extremely effective security measure. It is one of the best ways to protect your data and accounts from unauthorized access. 2 factor authentication requires users to provide two pieces of evidence to prove their identity. This could include a combination of something they know (like a password), something they have (like a phone or token device) or something they are (like a fingerprint). With 2 factor authentication, even if someone were to gain access to your password, they would still need to enter the additional authentication information to gain access to your account.
