Mork That isn't a change that 1Password itself can make. The websites you have accounts with will have to add support for Passkeys and offer a method for changing from password-based authentication to Passkey-based authentication. Passkeys and passwords will likely continue to co-exist for a long time to come. And there may be sites/services/systems that never adopt Passkeys. It isn't as though January 1 everybody is going to drop passwords and start using Passkeys, as nice as that might be. 😉
Whether you have Passkeys, passwords, or a mix of both, 1Password will be able to store them for you.
