Password Generator for Developers How to Create Secure API Keys Access Tokens and Cryptographic Salts

You are building an API. You need: access tokens for authentication, API keys for third-party integrations, and cryptographic salts for password hashing. Each requires a long, random, unguessable string. You could type random characters on your keyboard. That is not random. Human-generated "randomness" follows patterns — patterns that attackers exploit. You need a password generator configured for cryptographic randomness.

What Developers Need from a Password Generator

Access tokens: 32-64 characters, mixed case + digits, no symbols (symbols can cause issues in HTTP headers). Example: a 64-character token has 384 bits of entropy — effectively unguessable. Use the generator with these settings.

API keys: 32-40 characters, mixed case + digits, often with a prefix for identification. Example: sk_live_ + 32 random characters. The prefix identifies the key type. The random string is the secret. The generator creates the random string. You add the prefix.

Cryptographic salts: 16-32 characters, full character set including symbols. The salt is combined with the password before hashing. Each password gets a unique salt. The generator creates a unique salt for each password. The salt prevents rainbow table attacks. The generator ensures the salt is truly random.

The Difference Between Passwords and Developer Tokens

Passwords are for humans to remember (or store in a password manager). Developer tokens are for machines to use. They should be: longer (64+ characters — machines do not need to remember them), fully random (no patterns, no dictionary words), and never displayed to users. The password generator handles both. Configure the length and character set. The generator creates the random string. You integrate it into your application.
