Automatically rotate a secret - AWS Secrets Manager

Automatically rotate a secret

Secrets Manager provides complete rotation templates for Amazon RDS, Amazon DocumentDB, and Amazon Redshift secrets. For more information, see Automatically rotate an Amazon RDS, Amazon DocumentDB, or Amazon Redshift secret.

For other types of secrets, you create your own rotation function. Secrets Manager provides a Generic rotation function template that you can use as a starting point. If you use the Secrets Manager console or AWS Serverless Application Repository console to create your function from the template, then the Lambda execution role is also automatically set up.

Another way to automatically rotate a secret is to use AWS CloudFormation to create the secret, and include AWS::SecretsManager::RotationSchedule. See Automate secret creation in AWS CloudFormation.

Before you begin, you need the following:

  • A secret with the information you want to rotate, for example credentials for a user of a database or service.

To turn on rotation (console)

  1. Open the Secrets Manager console at

  2. On the Secrets page, choose your secret.

  3. On the Secret details page, in the Rotation configuration section, choose Edit rotation. The Edit rotation configuration dialog box opens. Do the following:

    1. Turn on Automatic rotation.

    2. Under Rotation schedule, enter your schedule in UTC time zone by doing one of the following:

      • Choose Schedule expression builder to build a schedule in a form. Secrets Manager stores your schedule as a rate() or cron() expression. The rotation window automatically starts at midnight unless you specify a Start time.

      • Choose Schedule expression, and then do one of the following:

        • Enter the cron expression for your schedule, for example, cron(0 21 L * ? *), which rotates the secret on the last day of every month at 9:00 PM UTC+0. A cron expression for Secrets Manager must have 0 in the minutes field because Secrets Manager rotation windows open on the hour. It must have * in the year field, because Secrets Manager does not support rotation schedules that are more than a year apart. For more information, see Schedule expressions.

        • Enter a rate expression for a daily rate, for example, rate(10 days), which rotates the secret every 10 days. The expression must include rate(). With a rate expression, the rotation window automatically starts at midnight.

    3. (Optional) For Window duration, choose the length of the window during which you want Secrets Manager to rotate your secret, for example 3h for a three hour window. The window must not go into the next UTC day. The rotation window automatically ends at the end of the day if you don't specify Window duration.

    4. Under Rotation function, do one of the following:

      1. If you already created a rotation function for this type of secret, choose it.

      2. Otherwise, choose Create function. In the Lambda console, create your new rotation function. If you see Browse serverless app repository, choose it, choose Show apps that create custom IAM roles or resource policies, and then choose SecretsManagerRotationTemplate. Otherwise, choose Author from scratch and use the Generic rotation function template as a starting point for your function. Implement each of the steps described in How rotation works.

        When your function is complete, return to the Secrets Manager console to finish your secret. For Choose a Lambda function, choose the refresh button. Then in the list of functions, choose your new function.

    5. Choose Save.
