Strength is an estimate based on length and structure. For important accounts, favour longer, unique secrets and a reputable password manager.

What makes a password strong?
These points mirror common security guidance for randomly generated secrets. They are a baseline, not a guarantee.
Long
Use as many characters as practical. For important accounts, aim for 14 or more characters or a multi-word passphrase.
Complex
Combine uppercase, lowercase, numbers, and symbols where policy allows. Avoid predictable patterns and obvious substitutions.
Unique
Use a different password or passphrase for each service so a single compromise does not cascade to others.

Short, practical answers about how this tool works and how to use it safely.
Passwords and passphrases are generated entirely in your browser using client-side JavaScript. The values are not sent to a server or logged by Constant Labs.
Generated secrets, options, and clipboard actions are not sent to analytics. If you allow cookies, lightweight anonymised analytics may record page usage, not the passwords themselves.
Generators remove human patterns and guessable choices. They make it straightforward to create long, random, unique passwords that are harder to brute-force or guess.
Yes. Reusing passwords turns one breach into many. Using a unique password or passphrase per service limits the impact of any single compromise.
Strong passwords are long, unique, and where policy permits, use a mix of character types. For high-value accounts, length and uniqueness matter more than clever substitutions.
A client-side generator reduces exposure, but your security still depends on the device. Malware, keyloggers, or compromised browsers can capture any text you type or copy.
A reputable password manager is usually the most practical option. For critical systems, follow your organisation’s policy and secure the manager with a strong, unique master credential.
