Overview
This tool creates random token strings for technical workflows where a predictable value would be unsafe or misleading. Choose Base64URL for URL-safe secrets, hex for checksum-like values, or alphanumeric when a system only accepts letters and digits. Use these tokens for test secrets, reset-link examples, temporary identifiers and development fixtures. Do not paste production secrets into shared tickets or public documents, and store real credentials in a password manager or secret store.
Use cases
- API key placeholderCreate a realistic token shape for docs, fixtures or local development.
- Reset link secretGenerate URL-safe random values for reset-flow testing and examples.
- Temporary test tokenProduce one or more throwaway tokens for QA, demos or mock data.
How it works
- 1
Choose the token length and number of tokens.
- 2
Select Base64URL, hex or alphanumeric output.
- 3
Add an optional prefix when your system expects one.
Examples
Base64URL token
Input: Length: 32; Count: 1; Format: Base64URL
Output: N4nK4y3zQx7fA9mP2sV6tB8cD0eR1uW5
A URL-safe token suitable for reset links or callback examples.
Hex token with prefix
Input: Length: 24; Count: 1; Format: Hex; Prefix: tok_
Output: tok_4f8a13c09d21b7e6a3c55f91
A prefixed hex token for systems that label token types.
Multiple test tokens
Input: Length: 16; Count: 3; Format: Alphanumeric
Output: k8Jm2Lq9Tz4Vn6Px
Several short test tokens can be generated at once for mock users.
FAQ
Which token format should I choose?
Use Base64URL for URL-safe secrets, hex for systems that expect hexadecimal values, and alphanumeric for strict forms that reject symbols.
Is the prefix counted in the random length?
No. The length setting controls only the random part. The prefix is added before each token after generation.
Can I use these tokens in production?
The generator uses browser cryptographic randomness when available, but production credentials should still be created and stored inside your normal secret-management process.
Why generate more than one token?
Multiple tokens are useful for fixtures, QA accounts and examples where each record needs a different secret-looking value.
