Processus d’authentification de l’utilisateur qui utilise un facteur en plus du nom d’utilisateur et du mot de passe, tel qu’un code par SMS." cta="Voir le glossaire">Multi-Factor Authentication</Tooltip> (MFA) and <Tooltip href="/docs/fr-ca/glossary?term=passwordless" tip="Sans mot de passe
Forme d’authentification qui ne repose pas sur un mot de passe comme premier facteur." cta="Voir le glossaire">Passwordless</Tooltip> at the tenant-level with the Unified Phone Experience.
