Auth0 Does Login Security | Auth0
Built-in security. At every step.
Auth0 helps you create trusted experiences with layered identity defences that power growth, not friction.
How Auth0 does security
We handle identity security, so you don’t have to.
Build trust at every step
Built-in identity security helps deliver reliable experiences your customers expect. Turn unknown users into trusted, repeat ones.
Secure smarter
Simplify access for trusted users. Get tougher on threats. Go passwordless, configure adaptive MFA policy for risk, strengthen API security, and much more.
Save time and resources
Automate and orchestrate identity security flows with no-code and pro-code Actions, and deploy faster.
Protection at every touchpoint
Identity is security, and it is more than SSO or an MFA checkbox. We take a multi-layer approach to securing every stage of the customer journey.
Bot Detection
Detect automated attacks like fake signups and credential stuffing using 60+ risk signals, ML-powered detection models, and respond with user-friendly challenges like Auth Challenge.
Tenant Access Control List
Stop known threats before they even hit your login flow. Filter suspicious traffic by IP, ASN, fingerprint, geography, or leverage Auth0’s curated threat intelligence lists to protect your apps and respond faster.
Supplemental Signals
Strengthen your security with a multi-layered defense by combining Auth0’s Attack Protection with third-party threat intelligence signals. Gain the granular visibility needed to trigger smarter, risk-based step-up challenges.
Brute-Force Protection
Prevent high-velocity attacks on a single user account by detecting repeated failed login attempts, blocking the IP, and alerting the affected user.
Suspicious IP Throttling
Prevent high-velocity attacks on multiple user accounts. Detect and block traffic from any IP address that rapidly attempts too many logins or signups.
Passwordless
Offer more secure and easy alternatives to passwords like phishing-resistant passkeys. Allow users to log in quickly and securely the same way they unlock their mobile devices.
Breached Password Detection
Prevent known breached credentials at sign-up, login, or password reset. Detect use of compromised credentials, block, and notify the user in real-time.
Credential Guard
This is our advanced version of Breached Password Detection. Detect compromised credentials faster with a dedicated security team and support for 35+ languages and 200+ regions.
Adaptive MFA
Set up a contextual and step-up MFA policy to assess risk signals like new devices, networks, locations, and untrusted IPs. Use out-of-the-box risk scoring or configure step-up policies to prompt for MFA only when the risk is elevated.
Continuous Session Protection
Monitor and manage user sessions with custom logic in Actions. Prevent session hijacking and revoke suspicious sessions. Set custom timeouts for session or refresh tokens.
Highly Regulated Identity
Step up security and privacy for sensitive customer interactions with Strong Customer Authentication (SCA) and Financial Grade APIs (FAPI). Gain more control over your encryption keys for your compliance requirements with Customer Managed Keys.
Universal Logout
Elevate security for your business customers using Okta Workforce Identity by automatically logging users out of SaaS apps when a logout or deprovisioning event occurs.

Frequently asked questions
Can I block malicious traffic by IP or geography?
Yes. Auth0 lets you block or allow traffic using Tenant Access Control List (ACL) based on IP address, ASN, device fingerprint, or geographic location. This helps stop malicious requests, like high-velocity attacks or traffic from risky regions, before they reach your login flow.
How does Auth0 protect against brute-force and credential stuffing attacks?
Auth0 uses a layered defense approach to improve security before, during, and after login. Identity threats such as brute-force attacks and credential stuffing are addressed across the full authentication flow, not just at the point of login, to reduce risk at every stage of the customer journey.
Does Auth0 detect bots and prevent fake signups?
Yes. Auth0 includes Bot Detection that identifies and mitigates automated attacks such as credential stuffing and fake account creation. It uses statistical models, IP reputation, and traffic pattern analysis.
How does Adaptive MFA improve login security?
Adaptive MFA evaluates each login attempt using contextual signals such as device, location, and IP reputation. If the login is considered high risk (low confidence score), Auth0 triggers a step-up MFA challenge.
What is Breached Password Detection and why does it matter?
Breached Password Detection helps protect your application from account takeover by identifying when users attempt to sign up or log in with credentials that have been exposed in known data breaches.
What is Credential Guard in Auth0?
Credential Guard is Auth0's advanced version of Breached Password Detection that helps identify compromised credentials significantly faster with broader coverage.
Does Auth0 support hardware security keys for MFA?
Yes. Auth0 supports FIDO2-certified hardware security keys (e.g., YubiKey). These phishing-resistant factors provide strong authentication by requiring physical possession of the device.
