I am new to the forums and looking for help on an annoying problem that has only developed since I applied the win 10 may update. I use the firefox browser and check emails by using a password manager to open outlook in the firefox browser. Before the update outlook just opened, but now I get a message asking for a security key. This is odd as I do not use the security key feature. even odder is that the message says it originated from firefox. I can still get to my emails but now have to cancel the warning message, then select back on the next box, and then input my email and finally my password. I know windows are pushing the new security key feature but this seems very user unfriendly and of course it may also be firefox causing the problem.
I would be grateful for any advice. Thank you all.
