About
The rel="dns-prefetch" attribute on 
HTML <link> elements instructs web browsers to resolve domain names for external resources before those resources are requested.
It is commonly used for third-party domains serving scripts, fonts, analytics, advertisements, or media files, helping reduce DNS lookup latency and improve loading performance for external connections.
OAuth is an open standard authorization protocol that allows applications to obtain limited access to user accounts without sharing passwords across web, mobile, and desktop environments.
It uses token-based authorization with access and refresh tokens, lets users grant specific permissions to applications such as access to profile data or contacts, and is widely adopted by online service providers such as 
Google, 
Facebook, 
Microsoft, and 
GitHub.
