  +[TIP]
  +====
  +Set this configuration property to different values for different environments (dev, test, prod) so you can know at a glance which environment you are connected to.
  +====
   
   The end-user can also be given the choice of changing the theme:
   
  
positive.code: `rememberMe.encryptionKey`
  | any string +
  (in prod, a random UUID each time)
  |Encryption key is used to encrypt the rememberMe user/password.  +
  
  Apache Isis leverages link:http://wicket.apache.org[Apache Wicket]'s rememberMe support which holds remembered
  user/passwords in an encrypted cookie.
  
  If a hard-coded and publicly known value were to be used (as was the case prior to `1.13.0`), then it would be possible for rememberMe user/password to be intercepted and decrypted, possibly compromising access.
  This configuration property therefore allows a private key to be specified, baked into the application.
