I have been using the vault to store my passwords for a long time but yesterday and today I haven't been able to open it. Instead of asking me for my password only, it asks me for username and password (though it pre-fills the username) and when I input the password there is a delay or it might ask me to complete an anti-bot box with the numbers from a photo. But the end result is that it returns me to the first sign in screen. I've rebooted the PC a couple of times but no change.
