A passkey is a faster and secure way to sign in to Preno without typing a password. Instead of remembering a password, you unlock your account using the same thing you use to unlock your device — your fingerprint, face, or PIN. This guide shows you how to create a passkey and use it to sign in.
Your fingerprint or face never leaves your device. Preno never sees it, receives it, or stores it — your device does the checking and simply confirms to us that it's you. If you'd rather not use your fingerprint or face, your device PIN works just as well.
Before you start
You'll need to be signed in to Preno on the device where you want to set up the passkey.
You'll need multi-factor authentication (MFA) set up on your account. A passkey is an additional way to sign in, not a replacement — you'll still need your authenticator whenever you sign in with your username and password.
Passkeys work with most up-to-date browsers and devices. If your browser or device is older, you may not see the option.
You can store passkeys in your password manager (Microsoft, Google, or Apple) so make sure they're ready when you sign in.
Set up a passkey
1. Go to Account Security
Click on your name in the top right corner of the Preno menu bar, then go to your Profile page.
Scroll down to the Account Security section.
Find the Passkeys area.
2. Create a new passkey
Select Create passkey.
Enter your authenticator code when prompted. This confirms it's really you before a new sign-in method is added to your account.
After this, your browser or device takes over to finish setting up the passkey. You'll be asked where to save it and then to confirm it's you. These prompts come from your browser or device — not Preno — so they look a little different depending on whether you're using Chrome, Safari, Edge, Windows, or your phone.
3. Choose where to save it
Save your passkey to a password manager, including:
Saving it to a password manager means the passkey is available across your devices, so you can sign in from more than one place.
4. Confirm it's you
When your device prompts you, confirm with your fingerprint, face, or device PIN. That's your passkey created — it will now appear in the Passkeys area of Account Security.
Sign in with a passkey
On the login screen, select Sign in with passkey.
If you have more than one passkey on the device, choose the one you want to use.
Confirm with your fingerprint, face, or device PIN. You're signed in — no password required.
Do I still need to enter my authenticator code?
Not when you sign in with a passkey. Your passkey confirms it's you, so there's no password and no six-digit code to type.
You still need your authenticator set up, because signing in with your username and password is always available — and that route asks for your code every time. There are two ways in:
Sign in with passkey — fingerprint, face or device PIN. Nothing else needed.
Sign in with username and password — your password, then your six-digit authenticator code.
Keep your authenticator and backup codes up to date either way. They're what gets you in when you're on a device that doesn't have your passkey.
Your passkey is tied to the device or password manager you saved it to. Keeping your authenticator set up means you can always sign in from anywhere else.
If you lose the device with your passkey
You won't be locked out. A passkey saved to a password manager (Microsoft, Google, or Apple) syncs across your devices, so you can sign in from any other device signed in to that manager.
A passkey saved only to the lost device is gone with it — but you can still sign in with your password and authenticator, then set up a new one.
Manage your passkeys
You can rename or remove a passkey any time from the Passkeys area in Account Security. Remove a passkey if you no longer use the device it's stored on.
