Signing in to Pine
Sign in at app.pinespace.com/signin. Enter your Pine address or username first; Pine then asks for your password, or lets you use a passkey if you have added one to your account.
One sign-in covers the whole suite: Mail, Calendar, Drive, and Pass all share the same Pine session, so signing in once signs you in everywhere.
To sign out, open the account menu (your avatar at the top right of any Pine app) and choose Sign out.
Passkeys
You can add passkeys to your account from the Identity surface (account menu, then Manage your Pine identity). A passkey signs you in with your device's screen lock instead of your password, and can also verify you when you reset your password.
