Yeah, NOT changing regularly is a big failure to understand how hackers think.

There are thousands of apps nowadays, and its literally impossible for everyone to know at all times what gets hacked, leaked, exploited, etc. This is why, banks and very high security things, have time sensitive rotated things... where depending on technology, these things are rotated to avoid brute force attacks, process failures or human misshandling.

Anyhow, time for hardening and cleaning up more this weekend.
