I am constantly getting message on my samsung phone when I go into my emails "to use this acccount, you need to verify your identity. Tap your account below to sign in".  When I sign in with correct password, I bounce back to past message.  I have created new passwords a couple of times, which works for a try or two, and then reverts to message re verification.  Sometimes, it works to turn my phone off and on, but only occasionally. 

At the same time my thunderbird email program on my laptop stopped being able to bring in emails.  Message that it is "downloading message in inbox" but they don't arrive.  Again, one time this went away and I got emails.   Now thunderbird is requesting my password and then says "login failed".  

This has been going on for several days.  Since it is happening on two devices with shaw mail I think that is where the problem is.  I can access shaw webmail still, with the same password.
