Character restrictions apply to some passwords.
The vRealize Automation administrator password that you define during installation must not contain special characters. As of this version of vRealize Automation, the following special characters are known to cause errors:
Double quote marks (")
A trailing equal sign (=)
Non-ASCII or extended ASCII characters
Passwords that contain special characters might be accepted when you assign them, but cause failures when you perform operations such as saving endpoints or when the machine attempts to join the vRealize Automation cluster.
