Random Strong Password Generator

Information

Password and Security Tools

Choose a focused tool based on the value you need. Secret input remains inside the isolated secure origin.

Create passwords and passphrases

Password GeneratorCreate a random account password from a configurable character pool.Passphrase GeneratorSelect independent words from the documented EFF long word list.Wi-Fi Password GeneratorCreate a printable WPA Personal passphrase within the standard length range.Bulk Password GeneratorCreate up to 100 independent values locally for controlled provisioning.

Analyze assumptions and patterns

Password Strength CheckerEstimate pattern-aware guessing resistance without sending the password.Entropy CalculatorCompare theoretical search spaces for uniformly random passwords.Brute-Force Time CalculatorExplore explicit online and offline guess-rate assumptions.

Generate development and numeric values

Random String GeneratorCreate test strings and identifiers from a custom pool.PIN GeneratorCreate one or more numeric PINs for systems with enforced retry limits.

These tools generate values; they do not create a complete token, credential-distribution or access-control system. Production authentication tokens require server-side expiry, scope, secure storage, rotation and revocation.

Privacy model shared by every tool

Every tool is self-hosted on the separate secure origin. The frame contains no third-party scripts, analytics, ads or storage. The main content site cannot read the generated or entered secret. It receives only frame sizing and allowlisted event names such as generator_used, never the value, length result or strength result.
