UPS does this in a particularly shitty way. They don't make you select country during login. There's a country selector at the top of every page, and if you don't select the right country before logging in, everything works up until you try to submit the completed shipping form, then it gives a cryptic error like "please check address". You have to log out, select the right country, log in, and fill out the entire form again.
@foone that might mean they only keep your data in your country. Might, could also be just giving you that impression. Not all countries like it when you store banking data elsewhere.
@foone also, two-step logins where you enter your username or email, click next, then get prompted for a password, because they've accumulated a bunch of different auth providers and also have different "estates" for individual orgs with conflicting requirements and can't figure out how to glue all of those together in a coherent fashion.
