Signing In

When you sign up, Cadence emails you a six-digit code and a confirmation link. They are two presentations of the same one-time token, so it does not matter which you use - but once you have used one, the other stops working.

1. Sign up. The screen that follows reads We’ve sent a 6-digit code to with your address beneath it.
2. Type the code into the field. It submits itself the moment the sixth digit lands, so there is usually no need to tap Verify email. On an iPhone the code is offered above the keyboard, so one tap fills the whole field.
3. Or open the email and tap the link instead - same destination.

If nothing arrives, Resend confirmation email issues a fresh code and retires the old one. If you already confirmed on another device, Already confirmed? Sign in takes you to the sign-in screen - confirming in a browser establishes the session there, not on the screen you are still looking at.

Signing up works in three places: on the web, in the iOS app from the App Store, and in the Android app from Google Play. It is not a web-only step, and you do not need to start on a computer before installing the app.

What differs is only how the subscription is paid for - each store handles its own purchase, while the web goes through card checkout. See Account & Subscription.

Enter your email and password and tap Sign In. If two-factor authentication is on, a six-digit code screen follows.

Forgotten it? Forgot Password? on the same screen emails a reset link. That link deliberately opens in your browser rather than the app, so you can recover from a device that does not have Cadence installed.

A passkey replaces the password with your device’s own unlock - face, fingerprint or screen lock. It cannot be phished, guessed or reused on another site, and there is nothing to remember.

1. Sign in normally, then go to Settings → Security.
2. On the Passkeys row, tap Set up and follow your device’s prompt.
3. Next time, tap Sign In with a Passkey at the top of the sign-in screen.

The Passkeys row is hidden on any device that cannot support them. Your password stays on the account as the fallback.

In the mobile apps, Cadence can use your device’s biometric check to sign you in and to unlock the app again later. The control takes its name from your device, so the row under Settings → Security reads Face ID, Touch ID or, on Android, Biometrics. On the sign-in screen the button reads Sign in with biometrics.

• Turning it on needs your password, because the app replays it behind the scenes when your face or fingerprint checks out. If you signed in with a passkey, you will be asked to type the password once to enable it.
• It is per device, so each phone or tablet is set up separately.
• Changing the faces or fingerprints registered on your device invalidates the stored credential by design - re-enable it from Settings if that happens.

Coming back to the app does not prompt for your face or fingerprint every time. It is a threshold, not a habit: the check is asked for once the app has been in the background for more than 30 minutes. Swap to another app for a moment and come straight back, and Cadence is simply there.

Two-factor authentication adds a one-time code from an authenticator app on top of your password, set up from the Authenticator App row under Settings → Security. It comes with a set of single-use recovery codes for the day you lose the authenticator.

Both are covered properly in Security, including what signing in with a recovery code does to your existing two-factor setup. Read that before you need it rather than after.
