Auth0
Secure, scalable user authentication for apps and AI
What is Auth0?
Try Auth0Auth0 helps you secure sign-in with multi-factor authentication (MFA) that’s designed to be flexible and less painful for users. The platform supports approaches like Adaptive MFA, step-up protection for sensitive areas, and modern phishing-resistant authentication such as WebAuthn and passkeys/FIDO2. Auth0 also offers Auth0 Guardian push notifications to replace manual codes and SMS with a simpler prompt.
What is Auth0 Multi-Factor Authentication (MFA)?
Auth0 Multi-Factor Authentication (MFA) adds an extra verification step to login so accounts are harder to compromise. Auth0’s MFA experience is designed to balance strong security with a smoother user experience by using flexible factors and risk-based prompts.
How does Adaptive MFA work in Auth0?
Adaptive MFA optimizes security without constantly challenging users. It only prompts for additional authentication when a login seems risky, so you can keep protection robust while reducing unnecessary interruptions.
Can users choose different MFA methods with Auth0?
Yes. When MFA is enabled, Auth0 lets you support multiple authentication factors so customers can choose what works best, such as one-time passwords, SMS notifications, or biometrics. Auth0 also supports WebAuthn for phishing-resistant authentication.
What is Step-Up MFA in Auth0?
Step-Up MFA enforces stronger authentication only when users access sensitive parts of your application. This lets you apply tighter security where it’s needed most, instead of requiring the highest level of verification for every login.
How does Auth0 Guardian improve the MFA experience?
Auth0 Guardian uses push notifications to authenticate users without manual codes or SMS. It’s positioned as more secure, faster, and easier for users than traditional MFA prompts.
Does Auth0 support FIDO2 and passkeys for MFA?
Auth0 supports FIDO2 and passkeys, including phishing-resistant sign-in using WebAuthn.
