Android 14’s platform Credential Manager supports multiple password managers simultaneously and lets third-party managers save and retrieve passkeys. When Android 14 launches, 1Password, Dashlane, Keeper, and Okta will support Credential Manager (ie. passkeys on Android).
On Android 13 and lower, the Credential Manager is backed by Google Password Manager – which is part of Google Play Services. Credential Manager supports passwords on Android 4.4+ but passkeys only on Android 9+, according to the documentation.
