The future is passwordless – but today maybe not. Hanko provides a beautiful login that allows you to meet your users where they are, and carefully guide them into a world without passwords. For better security, higher conversion rates, and happier users.

Passkeys and passcodes

This is our recommendation: Modern and secure, utilizing passkeys instead of passwords. It also includes a fail-safe fallback login option with passcodes and email verification during sign up.

OAuth + passkeys

Social logins can be added as an onboarding and authentication option and work exceptionally well when paired with passkeys.  The next major release of Hanko will also allow you to set up social logins as the only option for logins, as this has become increasingly popular lately.

Passkeys, you can play around with them on passkeys.io but hopefully you will see them everywhere soon. The web is bugged in that we didn't have a sane auth layer. This is the solution. The web will be 10x better with effortless secure auhtentication.
