Password & Key-like Generator

Generate strong passwords, passphrases, and private-key-like strings. Includes entropy/strength indicators and copy utilities.

Password & Key‑like Generator creates strong passwords, passphrases, and crypto‑like strings. It’s built for environment bootstraps, staging secrets, and test data—clearly labeled to avoid production misuse.

Key features

  • Password mode with length and charset toggles
  • Pronounceable option
  • Passphrase mode with separators and suffix options
  • Entropy display and copy actions

How it works

Choose a mode (password, passphrase, key‑like), then tune length and character sets. Entropy estimates help you select safe defaults. Premium adds key‑like patterns (Base58, UUID, PEM‑style) with clear disclaimers.

Step-by-step usage

  1. Select a generation mode.
  2. Set length/word count and allowed characters.
  3. Copy the result or generate a new one; avoid reusing in production secrets without proper review.

Examples

Create a strong password

Length 16 with upper/lower/digits/symbols. Copy and store in a secrets manager.

Generate a passphrase

Four words with hyphen separators and an optional numeric suffix.

(Premium) Key‑like string

Base58 or PEM‑style text for test environments (not real cryptographic keys).

Security & privacy

Where applicable, processing runs locally in your browser. Inputs are not logged or sent to external services. Premium features inside the app use Supabase Auth to protect access. For sensitive work, prefer local files and avoid sharing secrets. Outputs include copy and download actions to minimize manual transcription errors.

Accessibility

The tool supports keyboard navigation and screen readers with ARIA labels and descriptive messages. Focus order is logical, and error messages use human‑readable language. These docs maintain proper heading hierarchy and color contrast, and the app version includes skip links and live regions where appropriate.

Limitations & disclaimers

Some advanced capabilities are available only in the DevToolsHub app with a premium plan. The static documentation does not execute code or store inputs. Where behaviors differ across runtimes (browsers, servers, language engines), treat outputs as representative and verify against your production stack when correctness is critical.
