How can I match all strings without the word "authorize" in them via regular expressions? I tried *(authorize){0}* to no avail.

Answer 1

/^(?!.*authorize).*/

This uses a negative lookahead to ensure that the overall pattern will match only if the expression "authorize" cannot match anywhere in the input.
