Best Practices Password is a Best Practices for dealing with Password from an accumulation from many Years of experience and a variety sources.

Best Practices Password is not JUST technical, but also about Business Best Practices

Do you REALLY need to store passwords? #

Number One Best Practice is to not do Password Storage Schemes at all. Nothing is more efficient than not doing it at all. If you can, use OpenID Connect or User-Managed Access.

Server Side Best Practices Password#

You SHOULD Use Server-Side Login throttling schemes to prevent Brute-Force Password Attackers

You MUST use Secure connection (HTTPS)

To HTTPS or not to HTTPS?[1]#

Unless the connection is already secure (that is, tunneled through HTTPS using SSL/TLS), your login form values will be sent in cleartext, which allows anyone eavesdropping on the line between browser and web server will be able to read logins as they pass through. This type of wiretapping is done routinely by governments, but in general we won't address 'owned' wires other than to say this: If you are protecting anything non-trivial, use HTTPS.

In essence, the only practical way to protect against wiretapping / packet sniffing during login is by using HTTPS or another certificate-based encryption scheme or a proven & tested challenge-response scheme (for example, the Diffie-Hellman-based SRP).

If you are using Passwords are NOT using a Secure connection, then all else is a waste of time.

Web Authentication#

NIST.SP.800-63B changes the requirements for memorized secrets (ie passwords) in several ways.

Password Periodic Changes#

Should an organizational Entity mandate regular Password Periodic Changes?

Use Multi-Factor Authentication#

A very effective way to prevent account compromise at the moment is to use Multi-Factor Authentication. The most common method for 2FA at the moment is by using One-Time passwords (OTP) - special codes you force your users to enter during login. However not every user can or wants to add this extra step, and not every website wants to force users through the friction of setting it up and entering codes all the time.

You SHOULD always give them the option. It's never been easier to add OTP 2FA to your login process using third-party Authenticator Apps. Both of those also have options for removing the friction of typing codes in favor of pressing a button on a smartphone, if your users have smartphones.

Whether you add one-time-password 2FA or not, a layer that NIST encourages, which is widely seen as Best Practice, and which I'd recommend. Rather than an “always on” approach to MFA, organizations need to use an adaptive, step-up approach based on context. Risk-Based Authentication requests leverage contextual information such as Geolocation, Internet Protocol Address, device Fingerprinting and time of day help determine whether the user is really who he claims to be

Beware of Password Anti-Patterns#

Password Anti-Patterns are common misconceptions about passwords that SHOULD NOT be used.
