Generated value

Overview

Identifier Forge generates unique identifiers, secure tokens, random passwords, and placeholder text for development and testing. From industry-standard UUIDs to modern Nano IDs and cryptographically secure tokens, this tool provides everything you need for creating unique identifiers in your applications.

How to Use

Select Generator Type
Choose from UUID v4, UUID v7, ULID, Nano ID, random token, or password generator based on your needs. Each type is optimized for different use cases.
Configure Options
Adjust length for Nano IDs and tokens, or toggle symbol inclusion for passwords. Most options use sensible defaults.
Generate and Copy
Click Generate to create a new identifier. Each click produces a cryptographically unique value ready to copy and use.

Use Cases

Database Primary Keys

Generate UUIDs (v4 or v7) for database primary keys. UUID v4 provides random IDs, while UUID v7 is time-sortable and optimized for database indexing, making queries faster in distributed systems.

API Keys and Tokens

Create cryptographically secure random tokens for API keys, session tokens, or authentication secrets. These tokens are URL-safe and suitable for secure communications.

URL Shortener IDs

Generate short, unique Nano IDs for URL shorteners or public-facing identifiers. Nano IDs are shorter than UUIDs (21 chars vs 36) while maintaining collision resistance.

Test Data Generation

Create random passwords for test accounts or generate Lorem Ipsum placeholder text for mockups, prototypes, and UI testing.

Frequently Asked Questions

What's the difference between UUID v4 and UUID v7?

UUID v4 is completely random. UUID v7 includes a timestamp component, making it sortable by creation time and better for database performance. Use v7 for database IDs and v4 when time information should not be encoded.

Are the generated tokens cryptographically secure?

Yes, all generated IDs use the Web Crypto API (crypto.getRandomValues()) which provides cryptographically secure random numbers suitable for security-sensitive applications.

When should I use Nano ID instead of UUID?

Use Nano ID for user-facing IDs like shortened URLs or public identifiers where shorter length matters. UUIDs are better for internal systems requiring standardization and wide compatibility.

How secure are the generated passwords?

Generated passwords use cryptographically secure randomness with uppercase, lowercase, numbers, and optionally symbols. For production use, consider dedicated password managers with additional security features.

Concept Notes

Picking the right identifier

UUIDv4 is fully random, UUIDv7 introduces time ordering for index-friendly inserts, ULID mixes time and randomness with a sortable string, and Nano ID focuses on short, URL-safe tokens. Collision risks are low but not zero; production systems should still enforce uniqueness and tie IDs to authorization logic.
