Uppercase (A-Z)
26 possible characters
Doubles character space complexity. Significantly improves security.
Numbers (0-9)
10 possible characters
Adds numerical complexity. Important for strong passwords.
Symbols (!@#$)

Total possible combinations = (character set size)^(password length)
Frequently Asked Questions
How long should my password be?
For most accounts, 12-16 characters provide good security. For critical accounts (banking, email), use 16+ characters. The longer the password, the more secure it is.
Should I exclude similar characters?
Yes, if you need to type passwords manually. Excluding characters like i, l, 1, L, o, 0, O prevents confusion when reading or writing passwords.
Is it safe to generate passwords online?
Our generator runs entirely in your browser - passwords are never sent to our servers. However, for maximum security, consider using an offline password manager.
How often should I change my passwords?
Change passwords immediately if there's a security breach, every 90 days for critical accounts, and annually for less critical accounts. Focus on using unique, strong passwords rather than frequent changes.
