For maximum security, please refer to the following when creating a password.

User ID and its combination of digits or characters cannot be used as a password.

Repeated or consecutive numbers or characters cannot be used in a password (i.e. aaa, 1111)

You are highly advised not to use numbers that may be easily recognized by others, such as date of birth or resident registration number (social security number), as a password.

It is recommended that the password is changed every 3 ~ 6 months for tighter security.
