OAuth allows websites and services to share assets among users. It is widely accepted, but be aware of its vulnerabilities.

Since the beginning of distributed personal computer networks, one of the toughest computer security nuts to crack has been to provide a seamless, single sign-on (SSO) access experience among multiple computers, each of which require unrelated logon accounts to access their services and content. Although still not fully realized across the entire internet, myriad, completely unrelated websites can now be accessed using a single physical sign-on. You can use your password, phone, digital certificate, biometric identity, two-factor authentication (2FA) or multi-factor authentication (MFA) SSO solution to log onto one place, and not have to put in another access credential all day to access a bunch of others. We have OAuth to thank for much of it.
