Password Generator: free online, fast and secure
Weak and reused passwords are the main reason accounts get hacked. A strong password is long, random and unique for each site. This generator creates such passwords using your browser’s secure random number generator.
Choose length up to 64 characters, letters, numbers and symbols, avoid confusing characters like 0 and O, and see the strength in bits. Generate a list when setting up many accounts.
How to use Password Generator
- Set length and characters. Length slider and character checkboxes.
