Manage a security key

Sites can sign you in with a passkey or a hardware security key. On macOS and Linux, Sval has a page for managing the security keys you plug in.

You’ve bought a new security key and want to give it a PIN before you add it to your Fastmail account.

Steps

1. Plug in the security key.
2. Open Settings › Privacy and protection.
3. Under Security keys, select Manage security keys.

The security key manager opens in a new tab. There you can set or change the key’s PIN, see and remove the passkeys it holds, and add fingerprints if the key reads them.

Details

• The Security keys card isn’t in Settings on Windows.
• The security key manager is Firefox’s own, and works in Sval as it does there.
• Signing in with a passkey or a security key works on every platform. The site asks for it, and you follow its steps.
