Guide & best practices

Secret Generator for passwords, keys and passphrases

Generate cryptographically random secrets with controlled length and character selection – privacy-friendly and local.

Typical use cases

Useful for API keys, service accounts, database passwords, tokens and creating memorable passphrases.

How Balou generates secrets

Choose length, character sets and mode (password/API key/passphrase); Balou generates the secret locally with a secure random generator.

Secret best practices

Use sufficient length and entropy, use a unique secret per service and store secrets only in a password manager.

Frequently asked questions

How long should an API key be?

At least 32 random characters (≈ 128+ bits of entropy); longer is fine for automated keys.

Password or passphrase?

Passphrases of several random words are memorable, long random passwords are compact – both need enough entropy.

What does entropy mean?

A measure of randomness; more entropy (bits) means exponentially more effort to guess.

Are the secrets transmitted?

No, generation runs locally in the browser using the browser crypto API.
