How to Create a Secure Password
Choose password length (we recommend at least 12 characters) and character types: uppercase letters, lowercase letters, numbers, and special characters. The more types included, the more secure the password.
What is Password Entropy
Entropy measures password randomness in bits. Higher values mean harder to crack:
- Less than 28 bits: very weak, cracked instantly
- 28-35 bits: weak, cracked in hours
- 36-59 bits: reasonable, cracked in months
- 60-127 bits: strong, cracked in years
- 128+ bits: practically unbreakable
Password Security Rules
- Uniqueness: use different passwords for each site
- Length: minimum 12 characters, preferably 16+
- Variety: mix letters, numbers, and symbols
- Storage: use a password manager
- Two-factor auth: enable wherever possible
Generator Security
Our generator runs entirely in your browser. Passwords are created locally using a cryptographically secure random number generator (Web Crypto API) and are never transmitted to any server.
