I think there is a misunderstanding, I'm sure it's me.
The problem is:
I use Safari, I use the email login, and everytime that I login I need to wait for a number code sent by email, a new number. If use the previous doesn't work, and there is not any kind of sort of automate identification.
I use safari, I allow cookies and I don't wipe anything, but the pain in the ass subsist.
