PayPal says that the rollout will start on its website, rather than its app, and that you have to be running Chrome on Android 9 or up to access passkeys. If it’s available for your account, you may get a prompt asking if you want to create a passkey, which you can authenticate using the biometric system or passcode that you use to unlock your phone.

Passkeys are based on FIDO authentication standards, and are generally cross-platform compatible — though as PayPal shows, you may have to wait for a site or service to roll out support on every platform you use. Several password managers, including the ones built into iOS and Android, support syncing passkeys between devices, and there are ways to access them when you’re using a device that they’re not synced to as well.

Despite several big tech companies pitching passkeys as the key (no pun intended) to the passwordless future, they’re still relatively rare. 1Password has a page that keeps track of what sites and services support them, and while it does have some big names like Best Buy, Okta, Microsoft, and eBay, there’s still only 38 entries on the list. Even if there are actually double the number of sites that support passkeys, you’d still be pretty hard-pressed to ditch passwords for good at this point.
