Before running the set authentication password command, ensure that password authentication has been configured for the user interface.

The password is a string of 8 to 128 case-sensitive characters.
The password must contain at least two of the following characters: upper-case character, lower-case character, digit, and special character.
The special characters include spaces and the following:
`~!@#$%^&*()-_=+\|[{}];:'",<.>/?
Password entered in interactive mode is not displayed on the screen. The configuration file displays only the password encrypted using an irreversible encryption algorithm.
Users can press CTRL_C to cancel password modification in the interaction mode.
- If a password in cipher text is configured, enter a cipher text password contains 68 characters but users must obtain the password in plain text that is required for identity authentication.
If the password authentication is configured but the password is not configured for the user interface, the user cannot log in to the device.
If the set authentication password command is executed multiple times, the latest configuration overrides the previous ones. You can run the set authentication password command to change the local authentication password. After the password is changed, a user who wants to log in to the device must enter the latest password for identity authentication.
