Types of Password Security Alternatives

Password Security Alternative #1: Email Authentication

Email authentication is one of the most popular password alternatives because anyone with an email account can use it.

This method uses two-factor authentication as an extra layer of security. Instead of accessing an account with a password, users click a “sign in” button that directs them to a pre-written email. Once they hit send, they’ll have access to their accounts.

A special DKIM signature attached to each email helps confirm that the person is who they say they are.

Password Security Alternative #2: Biometrics

From face and fingerprint recognition to DNA matching, biometrics is a type of authentication method that uses biological factors to identify users. Since everyone’s biology is unique, this password alternative is one of the most secure options available. 

However, the challenge is that these systems are difficult and expensive to implement. Users need a specific device in order to access this authentication method.

Additionally, duplicating fingerprints is possible and if someone does access your account using biometrics, users can’t change them like they would a traditional password.


Password Security Alternative #3: Social Media Sign-In

Offering users the ability to login to your site using their existing credentials for their social media accounts can be a smart move in many situations.

Essentially, this option builds on the security features of the social media platform’s login system. Like email accounts, social media login credentials tend to be secure and reliable. Even if your site can’t offer the same level of tight credential security, take advantage of the security of the social media giants.

While some users might feel uncomfortable or distrustful of social media sign-in options, a large percentage of the population is willing to use it. After all, it reduces the need to create more and more passwords and it makes it much easier for new visitors to use your site.
