Updating play framework secret key for your application

Updating the application secret in application.conf

Play also provides a convenient utility for updating the secret in application.conf, should you want to have a particular secret configured for development or test servers. This is often useful when you have encrypted data using the application secret, and you want to ensure that the same secret is used every time the application is run in dev mode.

To update the secret in application.conf, run playUpdateSecret in the Play console:

[my-first-app] $ playUpdateSecret
[info] Generated new secret: B4FvQWnTp718vr6AHyvdGlrHBGNcvuM4y3jUeRCgXxIwBZIbt
