The U2F application can hold an unlimited number of U2F credentials and is FIDO certified.
FIDO2
The FIDO2 application allows for secure single and multi-factor authentication, and can store up to 25 resident credentials. These credentials, which are protected by user verification (PIN or fingerprint), enable passwordless login, where the YubiKey, unlocked by user verification and authorized by touch, can log you in to your accounts without entering a username or password.
