Until then, a unique long password with multi-factor authentication remains the right foundation. 1. Look for a passkey option in the security settings. 2. Keep existing recovery codes in a safe place. 3. Use a unique password from the generator or password manager for this service. ## **Three essential basics** ### **The private key stays protected** Your device, password manager, or security key holds the private part. A service receives only data it can use to verify a sign-in. ### **A passkey belongs to a domain** A passkey created for pwgen.de cannot test another website. Every application needs its own relying-party domain. ### **Account recovery still matters** Plan for device changes, lost security keys, and account recovery. Keep each service's recovery options safe. ## **What happens technically** Passkeys are built on WebAuthn: the service issues a challenge, your device signs it with the private key, and only the signature and the public key travel back. pwgen.de deliberately offers no test sign-in — no accounts are created here and no credentials are stored. [Read the W3C WebAuthn specification](https://www.w3.org/TR/webauthn-3/) ## **Frequently asked questions**
**What is a passkey? ** A key pair following the WebAuthn standard. The private part stays on your device, in your password manager or on a security key; the service only ever receives the public part and uses it to verify your sign-in. No secret that could be intercepted or guessed is ever transmitted.
**Does a passkey replace my password? ** At the service in question it can take over sign-in completely. The account still has recovery paths, though — a registered email address, recovery codes, sometimes a password that remains valid. From then on those are the weakest point and need securing.
**What happens if I lose my device? ** It depends on where the passkey lives. Platform and password-manager passkeys are usually synchronised across your devices. If it only exists on one device or a security key, you need a second passkey set up in advance, or the service's recovery options.
**Can I try a passkey here? ** No, and that is deliberate. A passkey is only valid for the domain it was created on, so a test passkey for pwgen.de would not work with any other service. On top of that, pwgen.de creates no accounts and stores no credentials.
