OAuth Authentication and Sync Service

One secure account that works across a whole family of apps. Your users sign up once, then every app signs them in with a single tap and keeps their settings and data perfectly in sync across all their devices, in real time.

What it does for you

• One account, every app: register once, and every app in your suite just works - no separate logins to juggle.
• Always in sync: a change on the phone shows up on the laptop in under a second, on every device.
• Private and isolated: each person's data is encrypted and kept strictly separate from everyone else's.
• Strong sign-in built in: two-factor codes, backup codes, push approval and passkeys, shared across all your apps.
• Add a new app instantly: bring another app into the family with no server changes, plus operator tools, metrics and encrypted nightly backups.

Behind the scenes every request is signed and protected against tampering and replay - the security is invisible to your users and always on.
