Many SaaS products, especially enterprise software, have a "login as a different user" feature that engineers use for debugging. It's good that non tech savvy users aren't always aware of the amount of information leakage that happens in situations where privacy is important. It would lead to a mega freak out. For example, if you receive SMS alerts from your bank about transactions, account balance etc. there are multiple engineers in the chain who have access to the information, but should not - * At the SMS gateway company to which the bank has outsourced the services * Your mobile service provider * People who run the SMSC (if the mobile operator has outsourced that) Unfortunately, there is no way to secure it end to end in its current form. The same is applicable to a lot of services.
