Instructions

Software Usage Instructions

Select an example or configure manually:You can first use “Load Safe Example,” “WiFi Password Example,” or “Test Account Example” to view parameters, or start configuring item by item from the password rules.
Set password rules:Set the random body length, fixed prefix/suffix, character types, custom characters, symbol scheme, and enable required character types, exclude similar-looking characters, exclude ambiguous symbols, avoid adjacent repeats, and deduplicate passwords as needed.
Set account rules:Choose to generate passwords only, random accounts, sequential accounts, or email-format accounts; you can set account prefixes/suffixes, length, character composition, starting sequence number, zero-padding digits, and email domain.
Set batch export:Enter the generation quantity, choose whether to include account, password, sequence number, and strength columns, and set the CSV, TXT, or JSON format, delimiter, line break type, file name, and ZIP name.
Proceed to the next page step by step:Each tab page has a “Next” button at the bottom. It is recommended to complete the settings in the order of password rules, account rules, batch export, and generated results.
Generate and check results:After clicking “Start Generating,” the page will display the first 20 results and show the total count, strength, and entropy information, so you can first check whether the format meets your requirements.
Copy or download:You can copy the first 20 preview items or all results; when you need to save the complete results, click “Download ZIP,” and the archive will include all export files and README instructions.

FAQ

A: Random accounts are suitable for generating irregular account names; sequential accounts are suitable for bulk user initialization; email-format accounts generate email-style accounts using the configured domain, making them suitable for import scenarios that require an email field.

A: Strength and entropy are estimated based on password length, character pool size, and composition rules. The higher the entropy, the more possible combinations there are to guess, but it is a rule-level reference and does not equal the overall security status of the account.

A: The page preview keeps the first 20 items so you can quickly check the format and rules. Copying all results or downloading the ZIP will include all generated results, not just the preview portion.

A: You can enable “Exclude confusing characters” in the password rules or account rules to reduce characters such as 0, O, o, 1, l, and I; you can also use a custom character set that keeps only characters allowed by the target system and easy to identify.

A: Larger quantities use more memory and computing time. It is recommended to enable split-volume export and set the number of rows per export file; if you need to generate a lot of data, process it in batches and download the ZIP promptly.

A: CSV is suitable for spreadsheet software and backend bulk imports; TXT is suitable for copying into scripts, command lines, or plain-text systems; JSON is suitable for program interfaces, configuration files, and automated processing workflows.

A: No. Accounts and passwords are generated on the current device page. The server does not receive the generated results, and there is no need to upload files or submit account or password data.
