  • An au ID password can be 8 to 32 characters long and may contain half-width alphanumeric characters and symbols.

    Entering a date format with consecutive numbers or repeating the same number will result in an error.

    Allowed characters: a to z, A to Z

    Allowed numbers: 0 to 9

    Allowed symbols: ~, `, !, @, #, $, %, ^, &, *, (, ), -, _, +, =

    • On some devices, the symbols "&" and "=" cannot be used in the password.
    • It is mandatory to use both half-width letters and numbers.
    • The use of symbols is not mandatory but using them along with alphanumeric characters increases the strength of the password.
