Passkeys

Set up passkeys for instant sign-in to the Resytech Dashboard using Face ID, fingerprint, or device PIN.

Passkeys let you sign in to the Resytech Dashboard using your device's built-in authentication — Face ID, fingerprint, or device PIN — instead of typing your email and password every time. This is especially useful when using the app as an installed PWA on your phone or tablet.

How passkeys work

A passkey is a secure credential stored on your device and protected by your biometric or PIN. When you sign in with a passkey:

Your device verifies your identity (Face ID, fingerprint, or PIN)
A cryptographic proof is sent to the server
You are signed in immediately — no email, password, or captcha needed

Your password is never sent during passkey sign-in. Each passkey is bound to a specific device and cannot be exported or copied.

Requirements

The Resytech Dashboard must be installed as an app (PWA) on your device
A device with biometric authentication or a device PIN set up
A modern browser: Safari 16.4+ (iOS), Chrome or Edge (Android/desktop)

Passkey sign-in is only available in the installed app. If you use the dashboard in a regular browser, you will still sign in with your email and password.

Setting up a passkey

When you sign in with your password for the first time after installing the app, you will be prompted to set up a passkey:

Sign in with your email and password as usual
A dialog will ask "Set up faster sign-in?"
Tap Set up passkey
Your device will prompt you for Face ID, fingerprint, or PIN
The passkey is registered and ready to use

If you tap Maybe later, you will not be prompted again on that device. You can always set one up later from your profile.

From your profile

Go to Profile (tap your avatar in the top right)
Select the Security tab
In the Passkeys section, tap Add Passkey
Enter a name for the passkey (e.g. "My iPhone", "Work Tablet")
Enter your current password to confirm
Your device will prompt you for Face ID, fingerprint, or PIN
The passkey is registered

You can register up to 10 passkeys per account — useful if you use multiple devices.

Signing in with a passkey

When using the installed app:

Open the app — the passkey prompt appears automatically
Authenticate with Face ID, fingerprint, or PIN
You are signed in

If you have passkeys on multiple accounts, your device will show a picker letting you choose which account to sign in to.

You can also tap Sign in with passkey on the sign-in screen to trigger the prompt manually.

Managing passkeys

To view or remove your passkeys:

Go to Profile > Security
The Passkeys section shows all registered passkeys with their name, creation date, and last used date
To remove a passkey, tap the trash icon next to it and enter your password to confirm

Removing a passkey from the dashboard does not delete it from your device's credential store. You may also need to remove it from your device's password/passkey settings.

Session expiry and passkeys

Your dashboard session expires after a period of inactivity (3 hours). Without a passkey, you would need to sign in again with your full email, password, and captcha.

With a passkey set up, the app will automatically prompt you for biometric authentication when your session expires. A single tap gets you back in — no typing required.

Troubleshooting

Issue	Solution
No passkey prompt appears	Make sure the app is installed as a PWA (not running in a browser tab). Passkey features are only available in the installed app.
"User verification required" error	Your device must have a PIN, Face ID, or fingerprint set up. Check your device's security settings.
Passkey stopped working	The passkey may have been removed from your device. Go to Profile > Security and register a new one.
"Passkey not recognized" error	The passkey may have been deleted from the dashboard. Register a new passkey from Profile > Security.
Cannot register a passkey	Make sure you are entering your current password correctly. You can have a maximum of 10 passkeys per account.
Want to switch to password sign-in	Cancel the passkey prompt (tap Cancel or press the back button). The regular sign-in form will be shown.

Security notes

Passkeys use the WebAuthn standard, the same technology used by Google, Apple, and Microsoft for passwordless sign-in
Your biometric data never leaves your device — the server only receives a cryptographic proof
Each passkey is bound to a specific website origin and cannot be used on phishing sites
Registering or removing a passkey requires your current password as an additional security step
Passkeys require user verification (biometric or PIN) on every sign-in — a simple touch is not sufficient
