When you need to create unique and secure passwords for multiple accounts, manual setup is both tedious and prone to repetition. The Bulk Password Generator uses a cryptographically secure pseudorandom number generator (CSPRNG) to batch-create high-strength passwords based on your custom length (4-64 characters), character types (uppercase, lowercase, numbers, special symbols), exclusion rules, and prefixes/suffixes. Passwords are the core credentials for digital authentication, and this tool can generate up to 100 random sequences matching your rules at once.
Q: Will the generated passwords be recorded by the server?
No. All generation and copying operations are completed locally in your browser without any network transmission or storage.
Q: How do I avoid generating confusing characters?
Enter the characters you want to avoid (such as 0, O, 1, l) in the exclusion box, and the tool will automatically filter out combinations containing them.
Please save your generated passwords immediately, as the data will be lost if the page is refreshed. For enhanced security, we recommend generating passwords that are at least 12 characters long and include all four character types. Avoid using this tool on public computers, and store your generated passwords in a secure password manager.
For systems with mandatory special character requirements, we recommend using the prefix/suffix feature to lock in the required symbols. Typical example: Set length to 12, check all character types, exclude "0O1l", set prefix to "Sec@", and generate 5 passwords. You will get high-strength bulk passwords like "Sec@xT9#kQm%" and "Sec@rF8&pLw$".
