OASIS 2FA Provider

Symantec says that the key to gaining unauthorised access to data is the theft of user credentials — such as passwords — using them to access accounts, and then hack into servers or databases, or deploy malware to steal sensitive information. Determining and remembering strong and unique passwords for multiple accounts can be difficult, so many users abandon safety for convenience.

You use 2FA so that the failure of one factor does not grant access to attackers. Therefore, if a password is one factor, then the second factor can protect you if the password turns out to be weak. Many, many companies fail to employ 2FA because its implementation can be labourious and costs prohibitively high.
