Rate Limits
Learn about the rate limits for different services and resources.
Authgear protects projects from an unusually high number of requests for services and resources. If a project receives too many requests in a very short period, it is likely to hit the limit. This feature is in place to prevent abuse and keep your application stable.
On this page, you'll find the details about the set limits for all Authgear services and resources.
Default Limits
The following are the default rate limits for any Authgear resource when a limit is not specified in this documentation:
60 requests per IP address in 1 minute (60/min).
10 requests per user per IP address in 1 minute (10/min).
Keep reading to learn more about rate limits for specific resources.
Authentication
The following section contains a table with the rate limits for usage related to authentication.
Limit per IP address: This column specifies the maximum usage of a resource or feature from a single IP address in a specific time interval.
Limit per user per IP: This is the maximum number of usage of a resource or feature for a single user, on a single IP address in a specific time interval. For example, user John.doe@example.com can only use TOTP 10 times in 1 minute from the same IP address.

How to Customize Verification Cooldown and Limits
The cooldown for user verification can be set to a custom value in the Authgear Portal. To do this, navigate to Authentication > Login Methods, then click on the Verification tab. You can set the cooldown (in seconds) in the Verification tab window using the Resend Cooldown Duration input field.
Other limits you can set from the Verification tab include:
Daily 6-digit OTP limit per user: Sets the maximum number of OTP a user can request in 24 hours.
6-digit OTP valid duration (seconds): The validity of an OTP code sent to a user. Authgear will no longer accept a code after the number of seconds specified here has passed since the user requested the OTP.
Number of attempts allowed for 6-digit OTP: This feature is turned off by default. When turned on, a valid OTP will become invalid after a user enters the wrong codes for the specified number of attempts.
Account Lockout
Account lockout is a temporary lock on a user due to them entering a wrong password, OTP, or recovery code more than the maximum number of attempts allowed.
Account Recovery
The table below shows rate limits for sending account recovery messages to users. It also includes a Validate per IP column, that specifies the number of times a user on an IP address can attempt account recovery within a given period.
Trigger per IP: The value under this column specifies the maximum number of account recovery requests that can be started from the same IP address per specific time (1 minute).
Validate per IP: This is the maximum number of account recoveries that can be attempted or completed from the same IP address per specific time (1 minute).
Cooldown per target: The minimum amount of time a user must wait before they can send another request to the same target (email address or phone number).

Messaging
The rate limits under this section apply to all messages (email and SMS) your Authgear project sends.
Limit per IP: This column defines the maximum number of messages that can be initiated from the same IP address per specific time. For example, a user can send a maximum of 200 messages in 1 minute without changing their IP address.
Limit per target: This is the maximum number of messages that can be sent to a target (email address or phone number) per specific time (24 hours). For example, an Authgear project with a Limit per target of 50/24hrs can send a maximum of 50 messages to the same email address in 24 hours.
