Sign In Error 'Login Rate Exceeded'

A Login Rate is the number of times a user attempts to log in to Salesforce within a given period of time.

Login Rate Limiting allows Salesforce to limit the number of login requests on a per-user basis to avoid performance impact on our services and improve security when logging into Salesforce.

What causes the Login Rate Exceeded error?

Login requests exceeding 3,600 requests per hour per user will be blocked, and the LOGIN_RATE_EXCEEDED error will be captured in the org's Login History.

How should I troubleshoot Login Rate Exceeded errors (see examples)?

We recommend that you monitor and review your orgs API integration users’ Login History to identify any users that may repeatedly generate calls to log in to Salesforce that exceeds the threshold of 3,600 requests per user, per hour. 

• Wait one hour and then attempt to login.
• If the issue persists, this may be caused by custom integrations or 3rd party applications.
• Incorrect username(s) and password(s) for integration users.

Note that Login History for requests that exceed the Login Rate Limit are no longer written for every failed attempt. One history row at least will be written for the LOGIN_RATE_EXCEEDED error to aid in troubleshooting. For more information please review Login History Entries Are Reduced When Login Rate Limiting Is Active.

How can I get more information?

If you have further questions or need assistance with identifying the process and user that may be exceeding the login rate limit, please reach out to Support by opening a case via Salesforce Help.
