No Invalid Characters
- A password may only contain valid characters. Valid characters include standard printable, human-readable ASCII

white space characters (spaces and tabs), function keys, arrow keys, and accented letters.
No Name or Login Name Fragments
- A password may not contain forward or reverse fragments of three or more characters from the owner's name or username.
For example, if John Doe has the username jdoe, his password cannot contain sequences such as jdo, ohn, or eod.
No Large Words
- A password may not contain words five characters or longer in length. Smaller words are allowed.
This includes common foreign words, formal nouns (like names),
and jargon not commonly found in traditional dictionaries.
No Alphabetic Sequences
- A password may not contain forward or reverse alphabetic sequences of three or more letters. The case of the letter
(uppercase or lowercase) does not matter. For example, these sequences are not allowed: abc, ZYX, mNo.

For example, these sequences are not allowed: 012, 876, 456.
No Keyboard Sequences
- A password may not contain keyboard sequences of three or more characters.
This includes horizontal, vertical, and diagonal rows of keys along with duplicate keys.
For example, these sequences are not allowed: asd, qaz, ji9, xXx, 222.
No Example Passwords
- A password may not match any example passwords used in anything you've seen online.
No Temporary Passwords
- If you request a password reset, it may be reset to a temporary password. Change it!
