Some warning to users: Changing iterations MAY corrupt your data:

This is incorrect.

> When you change the iteration count, you'll be logged out of all clients. Though the risk involved in rotating your encryption key does not exist when changing KDF iteration count, we still recommend exporting your vault beforehand.

That is when you change your master password, or rotate your encryption keys, not changing the number of iterations (as far as I can tell).

From what I read, changing the number of iterations is safe to do.
