About this tool
Rakuruno's password generator creates a random password in your browser. Generated passwords are not sent to a server or saved in your browser. Choose the length and character types to suit where you will use it.
Do not reuse the same password across services. When possible, use a password manager and multi-factor authentication. A passkey can also be a good option on services that support it.
Try a use case and check the result
Compare digits-only output with four character classes, excluding ambiguous characters and checking length and allowed characters.
Example buttons replace the inputs and settings above and calculate. Restore previous input steps back one example at a time. After trying multiple examples, repeat restore to return to your original input. This history is lost when the page closes.
Generate twenty characters using all four classes
Input and settings
Length 20 / Uppercase, lowercase, digits, symbols: on Exclude ambiguous: on
Expected result
Twenty characters containing each class at least once. Excludes 0, O, o, 1, I and l.
How to read the result
At least one character from each selected class is included, the rest filled, and the order shuffled. Digits-only output is labeled weak by the existing indicator even at length twelve because it has one class. That label is a length/class heuristic, not a breach-history or service-policy check.
Scope and limits
Length is 8–64 with at least one selected class. Preferences are saved in this browser; generated strings are not saved. Applying examples and restoring settings both generate fresh strings, without recovering prior output. Restore returns the original length/classes and saved preferences. This does not change any existing account password.
Verification: independent predicates check length, allowed characters and class presence. All settings are restored together before notifying the native input handler, avoiding conflicts with its keep-one-class rule. Checks include saved preferences and restoration after reload.

Settings for a 16-character digits-only password
Set the length to 16 and enable only Numbers to generate sixteen digits. With ambiguous characters excluded, 0 and 1 are omitted, leaving 2–9. This describes the settings, not a fixed password example.
The generator picks at least one character from each enabled character type, fills the remaining positions and shuffles them. Check the destination’s requirements and use your own password-management method to keep the result.
Frequently asked questions
Is my generated password sent to Rakuruno?
No. Passwords are generated in your browser and are not sent to a server.
Is my generated password saved?
No. The password itself is not saved. Only settings such as length and character types are kept in this browser for 30 days from the last save.
How long should my password be?
If you're unsure, aim for at least 15 characters. The service you use may limit the length or symbols it accepts.
Can I use the same password for several services?
It is not recommended. Use a different password for each service.
What if a site does not allow symbols?
Turn off “Symbols” and generate another password.

Inputs and storage
Keep any inputs or results you need before clearing. This browser saves only password length and character-set settings, not your working data or generated results. Site-data deletion or storage restrictions may remove settings. Settings are not restored when read 30 days or more after the last save.
Favorites and language preferences are stored separately and may be lost when site data is cleared. Tool resets and site-data deletion do not delete files already downloaded to your device.
