Secure Token ID Generator

Used by developers, writers, and creators worldwide.

A secure token ID generator creates the random strings used as session IDs, password reset links, API secrets, and webhook signatures. Any application that grants access without a stored password depends on tokens with enough randomness to resist brute-force attacks. This generator lets you set exact length (32 characters by default, giving 128 bits of entropy in hex), pick a format — hex, alphanumeric, or base62 — and generate several tokens at once. Hex keeps output clean for database columns and HTTP headers. Alphanumeric and base62 pack more entropy per character, making them ideal for URL-safe tokens in query strings. For production, always use a server-side CSPRNG like Node's crypto module or Python's secrets library.

How to use

  1. Choose your options above
  2. Click Generate
  3. Copy your result

Detailed instructions

  1. Set the count field to how many tokens you need in one batch.
  2. Set the length to match your security requirement — 32 for standard session tokens, 48–64 for API secrets.
  3. Choose a format: hex for protocol compatibility, alphanumeric for density, base62 for URL-safe output.
  4. Click Generate to produce the token list, then copy individual tokens or the full list.
  5. Paste tokens into your codebase as test fixtures, or use them as reference when implementing server-side generation.

Use Cases

  • •Prototyping password reset link tokens before wiring up a Node.js email workflow
  • •Generating base62 session IDs to verify correct length and entropy for a Django app
  • •Creating hex webhook secrets to test HMAC-SHA256 payload signature validation in Postman
  • •Seeding a staging database with 50 realistic invite-code tokens for Cypress E2E tests
  • •Drafting API key formats — including prefix conventions — before implementing backend generation

Tips

  • →For password reset tokens, use 48 characters in alphanumeric format — long enough to be safe, short enough to embed cleanly in a URL.
  • →Prefix tokens manually after generating them (e.g., 'sess_' or 'pk_') to make type-scanning your logs easier in production.
  • →If you need tokens that sort chronologically, combine a Unix timestamp prefix with a short random suffix rather than a pure random token.
  • →Test your database column width before deploying: a 64-character base62 token needs a VARCHAR(64) column minimum — easy to overlook.
  • →Generate a batch of 20+ tokens and visually inspect them for accidental patterns — consistent prefixes or repeated substrings signal a weak RNG.
  • →Hex tokens are easier to search and highlight in logs because they stick to lowercase a–f; consider this if debuggability matters more than token density.

FAQ

how long should a secure token be for password resets and sessions

At least 32 characters in hex (128 bits of entropy) for session tokens and password reset links. For long-lived API secrets, 48–64 characters is safer. Base62 reaches 128 bits in roughly 22 characters, so you can use shorter tokens without sacrificing security.

is this token generator safe to use in production

No — this tool is designed for prototyping and test-data generation, not production use. In production, generate tokens server-side with crypto.getRandomValues() in Node.js or Python's secrets.token_hex(), both of which use a cryptographically secure random number generator.

what's the difference between hex alphanumeric and base62 token formats

Hex uses 16 characters (0–9, a–f), so a 32-character hex token gives 128 bits of entropy. Alphanumeric and base62 use 62 characters, packing roughly 5.95 bits per character — a 32-character base62 token delivers about 190 bits. Base62 is also URL-safe, with no special characters that need encoding in query strings.
