How do I set up a passkey – Android?

Published
Updated

In this article, you will learn how to set up a passkey for somnio on your Android device and which requirements must be met.

With a passkey, you can log in to somnio securely and conveniently – without a password. Instead, you use functions of your Android device such as fingerprint, facial recognition, or a trusted device. For this to work, certain requirements must be met on your device.

What are passkeys?
Passkeys are a new way to log in without a password. Instead, something is used that uniquely identifies you, such as your fingerprint, your face, or a trusted device. Passkeys are faster, easier, and significantly more secure against hacker attacks. You can find more information about passkeys in the article "What is a passkey?".

To use passkeys in somnio, the requirements on your device must first be met.

Is your device ready for passkeys?
First, check whether your Android device supports passkeys.

  1. For smartphones or tablets (Android)
    For an Android device, you need either a fingerprint sensor or facial recognition. Here is how to proceed:
  • Open your device settings.
  • Go to Security or  Biometrics.
  • Search for fingerprint or facial recognition.
  • If one of these options is available, your device supports passkeys. Check whether the function is already set up. If not, follow your device’s instructions to set it up.

If you cannot find any of these options, your device is not compatible with passkeys. 

Is your software up to date?
To set up a passkey, you need current software versions. Therefore, please check before setup whether updates are available.

  • On Android devices: Settings → System → Software update

Install available updates so that your device supports the latest security features for passkeys. Also make sure that your browser (e.g., Google Chrome) is up to date.

My device does not have fingerprint or facial recognition – what now?
You can also use passkeys without biometric features. The following alternatives are available:

  1. Use of a trusted device
    If a device is 'trusted', it simply means that the device already recognizes you and you can confirm actions without entering a password. This can be, for example, your smartphone. Here is how it works:
  • Open the app or website that supports passkeys.
  • Select Set up passkey.
  • Follow the instructions to link your smartphone.
  • Then confirm the login via a notification on the trusted device.
  1. Login with device PIN or device password
    If no biometric features are available, you can also log in with a PIN or device password when using a passkey. In this case, the PIN is used as a substitute for biometric confirmation.

With these alternatives, you can use passkeys securely even without fingerprint or facial recognition.
