Your Password Can Be Phished. A Passkey Changes the Conversation.

A convincing login page can ask you to type a password, then hand that password to an attacker. Passkeys change what gets handed over. Instead of sending a reusable secret, the browser helps prove possession of a cryptographic credential tied to the service.

The important part is the destination

Web Authentication binds credentials to a relying party. That makes the website's identity part of the authentication process rather than something you must recognise perfectly every time. A copied logo on a different domain cannot simply collect the same password because there is no password being typed into its form.

This does not make every message containing the word passkey trustworthy. Someone can still trick you into approving another action, installing malicious software or weakening recovery settings. The surrounding account remains important.

Try the recovery thought experiment

Imagine losing your phone tomorrow. Could you sign in with another trusted device? Is your recovery email protected? Do you understand whether your passkeys sync through a provider or stay on one device?

Those questions matter more than a dramatic promise to become unhackable. A good login system reduces a common failure mode and gives you a workable recovery path. Before switching, read the service's recovery instructions and keep the backup method somewhere you can actually access.
