Why Choose a 20 Character Password?

A 20 character password provides extreme security with roughly 125 bits of entropy. It is completely immune to brute-force attacks - no existing or foreseeable computer can crack it.

Our generator creates truly random 20-character passwords using uppercase letters, lowercase letters, numbers and symbols, and excludes confusing characters like 1, l, 0 and O for readability.

20 character passwords are ideal for cryptocurrency wallets, password manager master passwords, enterprise administrator accounts, and any scenario demanding the highest level of security.

Frequently Asked Questions

Is a 20 character password overkill?

For everyday accounts, 12-16 characters is sufficient. But for cryptocurrency wallets, password manager master passwords, or admin accounts, 20 characters provides peace of mind with no real downside when using a password manager.

How long would it take to crack a 20 character password?

With about 125 bits of entropy, brute-forcing a random 20 character password at 10 billion guesses per second would take more than 10^21 years - vastly longer than the age of the universe.

Should I memorize a 20 character password?

Only if it is your password manager master password. For all other accounts, store it in a password manager so you never need to type or memorize it.
