Frequently asked questions
How is this different from the password generator?
It's the same underlying random generation, but framed for general-purpose strings rather than login credentials — useful when you need a random value that isn't specifically a password, like a placeholder or seed value.
What can a random string be used for?
Generating API keys or tokens for local testing, creating unique filenames, seeding test fixtures, or producing placeholder text that needs to look random rather than meaningful.
Can I control which characters appear?
Yes — choose which character types to include (letters, numbers, and so on) and the exact length, so the result matches whatever format you need.
Is anything about the generated string logged?
No. Generation and display happen entirely in your browser — nothing is sent to or stored on a server.
