There are no restrictions on the types of characters that can be used for a password. For security, it is recommended to create passwords consisting of uppercase or lowercase characters, numbers, and symbols. A password consisting of a large number of characters is less easily guessed by others.
In [Password Policy] in [Extended Security], you can specify a password consisting of uppercase or lowercase characters, numbers, and symbols, as well as the minimum number of characters to be used for the password. For details about specifying the password policy, see "Password Policy" in Specifying the Extended Security Functions.
