Create a bookmark to your inbox when logged in. Next time you log-in, immediately click your inbox bookmark so you can skip all the irritating "give us your phone number or you will suffer greatly" pages.

As for personal info, don't give it to them. Anyone who doesn't require it by law gets mis-info, this has served my privacy & security since the turn of the century. EVERYONE wants your phone number "for security" these days* , and yet, when they bungle their security yours goes out the window with a million+ others'.

*Your phone number is marketing gold to those who believe they value your personal, identifiable data more than you do.

edit: more asterisks, less italics

I had a terrible experience recently. It was so dumb I wrote a rant to a no-reply address they had sent me some options about.

I logged in from my only computer, they presented my recovery email addresses with check boxes. I didn't read the prompt, but I selected the one I still use (one was so freaking old--a netzero address). It seemed to remove it from the list, which was the opposite of the behavior I'd expect. I literally didn't care enough to add it back. If I get locked out of my yahoo account...so?

Anyway, then they sent me a "new device" email that said I should login from one of my normal devices. It was my normal device, I just hadn't logged in for maybe...years? Surely they can alter the logic to not say something so stupid.
