On one computer, I have recently found that LP asks for multi-factor authentication every day even though I say to trust it for 30 days. I asked the LP support team for a solution and they sent me the below.
Before I had a chance to try it out on that particular computer the problem went away. I’d like to know why, but don’t have a solution. Here’s one thing I noticed.
Under my list of trusted devices, the ones which seemed to be ok all had just letters and no dashes. I started to use the date to try and keep track and if I ran it all together like april132016desktop then this last attempt seemed to work. I’m not sure if that had anything to the solution, but now the problem seems to have gone away.
Here’s the LP solution.
