    Hey y'all, This is something I've been working on for a few months. It is a passkey system, similar to Apple Passkeys or a Yubikey, but it is entirely software based so you can sync credentials between devices. Passkeys (and FIDO devices in general) allow you to use public keys instead of passwords or codes to authenticate. For instance, you can just click "Approve" on the device/software instead of having to copy a code, and there are no passwords to phish. This is a new piece of tech, so website support for logins are still limited, but it can currently be used for 2FA anywhere a…

    I have been working on Sesame, an open-source password manager that keeps your vault local by default. You don't need an account to create or use a vault, and the hosted service never receives the vault itself.

(Linux support is yet to be released on v0.1.2, but currently is in the works.)
