Why use a 20-character password?

20-character passwords provide approximately 130 bits of entropy, making them virtually uncrackable by brute force. This is recommended for high-security accounts like banking, cryptocurrency, and password managers.

Is 20 characters overkill?

For most users, yes. However, for high-value accounts, cryptocurrency wallets, or if you want maximum security assurance, 20-character passwords provide an extra margin of safety.

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

With current technology, cracking a truly random 20-character password could take billions of years even with the most powerful supercomputers. It's effectively uncrackable.

What characters are included?

All character types: uppercase (A-Z), lowercase (a-z), numbers (0-9), and symbols (!@#$%^&*). This provides maximum entropy per character.

Should I use this for all my accounts?

You can, but 16-character passwords are sufficient for most accounts. Reserve 20-character passwords for your most critical accounts.

Are these passwords compatible with all websites?

Most modern websites support 20-character passwords. However, some older systems may have length restrictions. Check the site's password requirements.
