Auth0 can detect anomalies and stop malicious attempts to access your application. Anomaly detection can alert you and your users of suspicious activity, as well as block further login attempts. You can set preferences for notifications and decide whether to block a suspicious IP address or not.
Auth0 has two types of shields to handle anomalies and attacks.
A shield specifies the action you wish to take given a specific trigger. A trigger is a suspicious event that is detected when someone is trying to login to your system, or there may have been a breached password with another third party service.
Customize the actions in the Anomaly Detection section on the Dashboard.
- 10 consecutive failed login attempts for the same user and from the same IP address
- 100 failed login attempts from the same IP address in 24 hours or 50 sign up attempts per minute from the same IP address
For example, if a user with user_id1 signs in from IP1 and fails to login consecutively for 10 attempts, their log in attempt from this IP1 will be blocked. Another user, user_id2, signing in from IP1 will not be blocked.
Breached password detection
Every day, malicious hackers penetrate websites and applications, exposing thousands of email and passwords. Because it's common for users to use the same password to login to multiples sites, this poses a problem, not only for the hacked system, but to any application that shares those breached passwords.
Auth0 tracks large security breaches that are happening on major third party sites to help keep your users and system secure. By enabling breached password detection, when a trigger occurs, your users can be notified and/or blocked from logging in if we suspect their credentials were part of a published security breach. You can customize blocked account emails.
Frequently asked questions
Is the user notified at every login? We send one email every hour, regardless of the number of logins. For example, if a user tries to log in 200 times in 1 hour and 30 minutes, we will send 2 emails.
Is there a limit to the number of times a user will be notified? Users will only be notified once per hour.
How often does Auth0 email administrators when traffic is blocked using Brute Force Protection for multiple accounts? In the event of an ongoing attack, traffic can be blocked from thousands of IP addresses at a time. Auth0 will send a single email to each administrator every hour that traffic is blocked, regardless of the number of IPs involved in the attack.
For how long is the reset password link, included in the breached password email, valid? Password reset links are valid for 5 days.
Is there a test dataset of breached passwords? You can test with firstname.lastname@example.org as the email and Paaf213XXYYZZ as the password.
Does the breached password detection work when logging in using the Resource Owner password grant? Yes.
Does the breached password detection feature work with a custom database? Yes.
What Redirect URL applies to the Change password link included in the breached password notification email? The RedirectTo URL is the URL listed in the Dashboard in Emails > Templates > Change Password Template.
Is there a way to configure the Redirect URL and the length of time that the change password link is valid? You can configure the URL Lifetime and Redirect To values in the Dashboard by going to Emails > Templates > Change Password Template.
