1Password

1Password (and other popular password managers) are a great Passkey option.

1Password is an inexpensive and robust password manager that lets you create, use, and share passkeys. Your passkeys are protected by the same proven security that millions of people and thousands of companies trust to protect their most important information. With 1Password, you can use passkeys with confidence on all of your devices, anywhere in the world.

Other password managers such as Bitwarden and Lastpass may also be good options for you, depending on your personal preferences. Our recommendation for 1Password comes from our team's positive experience with their service and ease of use for Passkey authorizations on Defined.fi.

With 1Password installed, it will appear as an option when saving your Passkey.
