Passkeys are used to sign transactions in Splits. Passkeys are public-private key pairs that are saved in a password manager (e.g. iCloud, Google Password Manager, Yubikey, 1Password, etc) and require your biometrics (or a PIN) to activate.
You can add as many passkeys to your profile as you wish. You can do so by going to Settings > Personal > Passkeys > Add passkey.
When you add a new passkey, the private key is stored in your password manager, and the public key is stored on our servers. We never have access to your private key.
Most password managers work across devices, allowing you to seamlessly move between your phone, laptop, tablet, etc. For example, if you save a passkey in iCloud, you will be able to login and sign transactions on both your iPhone and Macbook without having to connect a wallet or type in a password/seed phrase.
In our experience, iCloud and Google Password Manager are the easiest and most reliable software providers. We also see folks using 1Password, BitWarden, LastPass and others.
For higher-value accounts, we’ve found Yubikeys to be the most reliable.
