What is the output format?
41 characters starting with an asterisk: MySQL 4.1+ PASSWORD() = * + UPPER(SHA1(SHA1(plaintext))).
Can I use it to create users?
It matches the legacy SET PASSWORD flow, but MySQL 8 deprecated this function; prefer native authentication plugins for new setups.
Will my data be uploaded?
No, all computations run locally in your browser.
