Free Secure Token Generator

API keys, session IDs, password-reset links, and invite codes all depend on one thing: unpredictability. The Secure Token Generator creates high-entropy tokens with your device's cryptographic random generator, in hex, Base64, or URL-safe Base64 — ready to paste into configs, databases, and URLs.

Private by design. This tool runs 100% in your browser — generated tokens are never uploaded, stored, or transmitted anywhere.

How to Use the Secure Token Generator

  1. Pick the token size — 32 bytes gives 256 bits of entropy.
  2. Choose the format: hex, Base64, or URL-safe Base64.
  3. Click Generate tokens.
  4. Copy a token and use it as an API key, session ID, or secret.

Features

8–128 byte tokens; hex/Base64/URL-safe output; batch generation; entropy display; copy buttons.

Benefits & Use Cases

Mint API keys, generate session identifiers, create password-reset tokens, or produce secrets for .env files and CI pipelines.

Tips

32 bytes (256 bits) suits almost every purpose. Store tokens hashed where possible (like passwords), transmit them over HTTPS only, and give each token an expiry.

Frequently Asked Questions

How is this different from a password generator?

Tokens are for machines, not humans: longer, no memorability constraints, and often URL-safe. The randomness source is equally strong.

What format should I choose?

Hex for database keys and maximum compatibility; URL-safe Base64 for tokens embedded in links (reset URLs, invites); standard Base64 when a spec requires it.

How much entropy do I need?

128 bits is plenty; 256 bits (32 bytes) is the comfortable default. Beyond that, you're guarding against physics, not attackers.

Should I store tokens in plaintext?

If you can verify by hashing (like API keys), hash them. For bearer tokens that must be looked up, encrypt at rest and limit exposure.
