Security Tips
A 20-character password with all character types has over 130 bits of entropy.

Consider using a passphrase as an alternative for passwords you need to memorize.
FAQ
Why 20 characters?
20 characters with a full character set provides over 130 bits of entropy, making it virtually impossible to crack with any known or foreseeable technology.
Is a longer password always more secure?
Yes, assuming randomness. Each additional character exponentially increases the number of possible combinations. A 20-character random password is billions of times harder to crack than a 12-character one.
Do all websites accept 20-character passwords?
Most modern websites accept passwords up to 128 characters. Some older systems may have a maximum of 16 or 20 characters. If needed, you can adjust the length here.
