I'm trying to access my vault via the web interface. I'm using LastPass.com to login with my master password I seem to get logged in for a brief second and then it flashes a message that it is logging me out. Sequence of what I see on the screen is 1) I enter email/master pass and submit, 2) the LastPass splash screen flashes for a brief moment, 3) an icon that looks like a vault flashes for a brief moment, 4) a "Logging out from LastPass..." screen flashes (this screen has a clock looking icon and at the bottom says "Please wait until we log you out."), 5) then a "You've been logged out from LastPass." screen for about a second, 6) and finally I see the login form page again.
Please note that I do know that my master password is correct. I was able to use it to login to this support area! Also, I haven't logged into my LastPass account for probably a year or so. A few minutes ago when I tried for the first time it didn't let me login and it sent me an email saying I was trying to login from an unknown/untrusted device, so I clicked on the button in the email that let me approve this device. But then when I tried to login again with my credentials it started doing this automatic logout thing that I described in the first paragraph (which is my current problem). I have a video of this login/logout sequence if that would help at all, let me know if I should share that.
Also, as far as I know I don't have any special login setup outside of the master password. I don't have 2fa setup for example. I've always been able to just put in my email and master password.
