Passwords are frustrating. We know they should be unique, but then they’re hard to remember. We know they should be complex, but then they’re even harder to remember and painful to create. Password managers mostly solve the problem for those savvy enough to use them and determined enough to set them up, but for the majority of the population, it’s an endless dance between compromises. So what’s the solution? There is no magic bullet here, but passwordless authentication is gaining mainstream adoption and promises to make life at least somewhat easier. Passwordless authentication describes a range of approaches that seek to authenticate users by other means. Often this either involves using an alternative authentication factor or else cleverly piggy-backing on a service that can be assumed to have already authenticated the user. For example, if we were to send a secret code to a specific email address or telephone number.
