Most VPN providers have a written policy regarding the collection of customer data as it relates to web traffic and history.  In short, yes, VPN providers technically can see your IP address, VPN login data, and some of your browsing data. Quality providers, however,  have a “no-log” policy, which means that they do not store customer traffic or any other information about customer behavior online.   Note that your VPN provider won’t be able to see your other personal passwords.
