Web Application Security: Passwords Checklist

Enforcing strong password policy and security best practices.
Minimum Password Length

Set a minimum password length of 12 characters.

Maximum Password Length

Allow users to use passwords with 64 characters or more.

Change Passwords

Allow users to change their passwords.

Allow Two-Factor Authentication Applications

Allow users to setup Two-Factor Authenticator (2FA) applications to prove a second stage of security. Do not use SMS/Txt based 2FA systems.

Example: Google Authenticator (Android or iOS)

Complexity Match Passwords

Require users to set passwords to a complexity match which at least has all of the following criteria: Uppercase, Lowercase, Numbers, and Symbols.

Store Password Using a Strong Hashing Algorithm

When storing password at rest, use strong one-way hashing algorithm/scheme along with a randomly generated salt per password.

Use Full Unicode Characters

Allow users to use the full Unicode character set.

Password Check

Verify that the password registered or updated by my users aren’t using a password found in the top 1,000 (or 10,000) breached passwords.

Password Strength Meter

Display to the user a “password strength meter” showing them the strength or their passwords. This provides the user feedback around the strength of their passwords.


– Don’t force users to periodically rotate/change their passwords
– Allow users to paste, use the browsers password helper, and user password managers while using my application
