Password Generator

Generate secure random passwords and memorable passphrases on your device. No generated value is uploaded, stored or logged by Convertr.

Generated values

Generated values exist only in this browser tab unless you copy or download them.

Estimated strength
Generate a value to see the entropy estimate.
0 bits

Generated passwords and passphrases appear here.

Secure browser randomness

Passwords use crypto.getRandomValues. The tool does not fall back to Math.random or server-side generation.

Local generation only

Generated passwords, passphrases and copied values are not included in analytics events or network requests.

Bulk export

Create up to 100 values, copy the full list, or download a plain text file for your own workflow.

Frequently Asked Questions

Does this password generator upload generated passwords?

No. Password and passphrase generation runs in your browser. Generated values are not sent to Convertr servers.

What random source does the tool use?

The tool uses crypto.getRandomValues from the browser Web Crypto API. If secure random bytes are unavailable, generation stops with an error.

Does Convertr store or manage passwords?

No. This page only generates values locally. It does not store passwords, manage accounts or remember generated values after you leave the page.

Password Generator

Generate random passwords or passphrases from selected length, character, and word options.

Input
Length, character sets, exclusions, or passphrase word and separator choices.
Output
Random password or passphrase candidates with an estimated composition summary.
Real limitations
Strength depends on random generation and chosen entropy; the estimate cannot guarantee account safety, and sites may impose different rules.
Privacy and data handling
length, character sets, exclusions, or passphrase word and separator choices is processed in this browser tab. Convertr does not receive or store it; closing or reloading the page clears the working state unless the tool explicitly offers a local download.

How to use this tool

  1. Provide length, character sets, exclusions, or passphrase word and separator choices in the tool controls.
  2. Choose the settings that affect random password or passphrase candidates with an estimated composition summary, then run the tool.
  3. Review random password or passphrase candidates with an estimated composition summary before copying or downloading it.

Common failure modes

Unavailable secure randomness, contradictory character exclusions, or a requested length too small for required groups prevents generation.

Useful example

Generate a 20-character password containing upper, lower, numbers, and symbols while excluding ambiguous characters.
