I'm just going to cross post this here as I'm also having trouble with my second password and maybe it's relevant or someone can help me out:
I'm also having trouble with my blockchain account specifically the second password. When I logged in on my phone today after about a month to try send some funds it asks you first for the second password which it didn't used to do. It was always the last thing before you finally sent the funds. However, when I put the password in it says incorrect password which it isn't and I'm 100% sure of that. All my funds are still there. I wonder if this is just an error with the updated app as the layout has changed a bit??? I think I've only ever been asked to input the second password once upon log on years ago when they changed their system up. It made me a bit worried but everything was fine. Anyone know whats up with this??? I'll try log onto my desktop wallet when I'm back on a safe computer and see if it's the same.
I've been using it for years and only really use it as a wallet on the go so don't have much in there. It was workign fine last month.
