About this utility
How to use Secure Password Generator
Generate strong passwords with browser cryptography, explicit character groups, and an entropy estimate.
What to provide
The optional note is never included in generated passwords. Choose length, count, and character groups below.
- Enter the optional value described above, or leave it empty to generate new values.
- Choose the options that match your intended result.
- Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.
What the result means
Cryptographically random passwords, one per line, generated only when you run the tool.
Privacy and safety
This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.
Limitations
- The entropy figure is an upper-bound estimate. Password policy, reuse, phishing resistance, account recovery, and password-manager security remain separate concerns.
