Minimum number of characters for password
For secure passwords, aim for a minimum of 16 characters, but longer is always better, and ideally include a mix of uppercase and lowercase letters, numbers, and symbols.
Here's a more detailed breakdown:
-
Length is Key:The longer your password, the more difficult it is for hackers to crack using brute-force methods.
-
Complexity Matters:Don't just rely on length; include a variety of character types (uppercase, lowercase, numbers, symbols).
-
Avoid Dictionary Words:Don't use common words or phrases, as these are easy to guess or find in password cracking databases.
-
Don't Reuse Passwords:Use unique passwords for each account to prevent a compromise from one account from affecting others.
-
Consider Passphrases:If you struggle with remembering long, complex passwords, consider using a passphrase (a memorable phrase) instead.
-
Use a Password Manager:A password manager can help you generate and store strong, unique passwords for all your accounts.
-
Enforce Strong Password Policies:If you are an administrator, encourage or enforce strong password policies for your organization.
-
NIST Recommendations:The U.S. National Institute of Standards and Technology (NIST) recommends a minimum password length of 16 characters.
-
CISA Recommendations:The Cybersecurity & Infrastructure Security Agency (CISA) recommends passwords that are "Long—at least 16 characters long (even longer is better)".
