Notes

Security note

Locally generated with crypto.getRandomValues for API keys and session tokens. Unlike UUIDs, length and charset are configurable.

Configure length, count, and charset for API keys, session tokens, and test credentials. Uses crypto.getRandomValues locally.

Quick start

  1. Pick charset

    Alphanumeric, hex, Base64 URL, or printable ASCII.

  2. Generate and copy

    Up to 100 tokens; length 4-512.

vs UUID

Tokens are length/charset configurable; UUIDs are fixed-format unique IDs.

Typical Workflow

When developing APIs, you often need unique access credentials for each client. Open the tool, set the token length to 32 characters, select a character set including uppercase/lowercase letters and numbers, then generate 50 tokens. Store these in your database to complete client authentication setup - all without writing extra code.

Testers can use bulk generation to quickly create test cases. For example, when simulating 1000 concurrent users, pre-generate tokens as test parameters. By customizing character sets to exclude special symbols, you ensure compatibility with specific systems. All operations happen locally in the browser without data exposure.

Examples

API key

Input

length=32, alnum

Output

32-char token

FAQ

Secure enough?

Uses browser CSPRNG; pair with a secrets manager in production.

Why are these tokens more secure than UUIDs?

Standard UUIDs have fixed formats with partially non-random bytes, while our tool generates completely random character sequences. Using crypto.getRandomValues API ensures cryptographic strength with adjustable length/charsets. A 64-character mixed token has far higher entropy than UUIDv4, ideal for high-security use cases.
