What are the allowed characters for a password of Atlas?

[#1]

I set up Atlas with AD authentication. And I heard that some users failed to log in and the others succeeded.

The users said that the users who failed to log in are using "@" in their password.

I know I should confirm by my eyes, but before to do that, I want to know what characters are allowed to use for a password of Atlas.

Could anyone please answer my question?

@Takefumi Oide,

Password should be minimum 8 characters with minimum one alphabet and one numeric. Unsupported special characters are " ' \ `

Below is the regex check for password in HDP 3.0

if not bool(re.search(r'^(?=.*[0-9])(?=.*[a-zA-Z]).{8,}$', atlas_admin_password)) or bool(re.search('[\\\`"\']', atlas_admin_password))
.
