A passkey is a way to sign in to rynda.io with your fingerprint, face or device PIN, with no password and no email code. The passkey lives on your phone or computer; rynda.io keeps only its public part, which cannot be used to sign in.
How to add a passkey
- Sign in to rynda.io with your email and password or with an email code.
- Open Account → Security and, under Passkeys, click Add a passkey.
- Confirm on your device: touch the sensor, look at the camera or enter your PIN.
- The passkey appears in the list with the device name and the date it was added.
After your first sign-in, your account also offers a passkey in a card at the bottom of the screen: Add a passkey does the same as the button in Security. Not now hides the offer on this device; you can add a passkey later in Settings.
How to sign in with a passkey
- Open the sign-in page and click Sign in with a passkey.
- Your device shows the passkeys saved for rynda.io. Pick your account.
- Confirm with your fingerprint, face or PIN. Your account opens straight away.
You do not type an email: the passkey tells us which account it belongs to.
Which devices work
| Device | How you confirm |
|---|---|
| iPhone and iPad | Face ID, Touch ID or passcode |
| Mac | Touch ID or your Mac password |
| Android | fingerprint, face or screen lock |
| Windows | Windows Hello: face, fingerprint or PIN |
You need a browser that supports passkeys: a recent Safari, Chrome or Edge. If your computer has no sensor of its own, the browser offers to sign in with your phone: scan the QR code with the phone that holds the passkey.
Passkeys synced by your device's cloud (iCloud, Google) work on all your devices signed in to the same cloud account, so you do not need to add one on each.
How many passkeys you can add
Up to 10 per account, for example your phone, work laptop and home computer. Remove a passkey you no longer use in Account → Security with Remove next to it.
Good to know
- One device, one session. Signing in with a passkey, like any other sign-in, ends the session on your previous device.
- Removed a passkey on the site. Your device does not know and keeps offering it. Signing in shows "This passkey is no longer linked to an account": sign in with your email and add it again. You can delete the passkey itself in your device's password settings.
- Working for a company. If you work in a company's account as its team member, you cannot add a passkey to that account: the account owner adds passkeys while signed in to their own account.
- Password and email code stay. A passkey adds a way to sign in; it does not replace the others. Lost your phone? Sign in with an email code and remove that phone's passkey.
- Deleting your account also deletes all its passkeys.
