- Do choose a password with at least 8 characters containing both alphabets and numbers and special characters.
- Do choose a passphrase no longer than 64 characters in length for added security, containing a series of words not commonly found in literature or music preferably with spaces, punctuations and unexpected characters that are unique or specific only to you.
- Do not use Weak Password. Weak Password includes:
- Password that can be found from dictionary.
- Password that is related to your personal information, such as birth date, telephone numbers, any IDs, license numbers, etc.
- Password that is related to names or places.
- Abbreviations of common phrases or acronyms.
- Sequences of numbers or characters, or consecutive keys on a keyboard.
- Do not use your computer account name, or the reverse of it, as the password.
