OSRS always ask me for Auth everyday I log in? I have my PC on all day and only turn off night time when I go to sleep.

This only happen for my alt but never asked for my main. I have "trust this computer for 30 days" checked always.

I was worried that someone was trying to log in my Alt everyday.

Now that I am doing some job and OSRS is asking for auth for my client's acc everyday as well..

Just wondering why is this happening?

My main is fine and doesnt ask me for 30 days.

I was having this problem awhile back with unsure whats going on with it. Id assume the crack down theyre doing

Been alot of issues with that.
You can try to remove your authenticator from that acc it don't work on and take it back on.
Might do the trick.
