{| class="wikitable" style="width:auto"

|-
! Feature !! OAuth 1.0 !! OAuth 2.0
|-
| '''Token Type''' || Uses signed requests (HMAC-SHA1) || Uses bearer tokens
|-
| '''Complexity''' || More complex, requiring cryptographic signatures || Simplified with no signature requirements
|-
| '''Security''' || Strong security due to signed requests || Security relies on HTTPS and short-lived tokens
|-
| '''Access Token Handling || Requires client secrets and cryptographic signatures || Uses bearer tokens and access tokens with expiration'''
|-
| '''Refresh Tokens''' || Not supported || Supported, allowing seamless re-authentication
|-
| '''Grant Types''' || Single flow for obtaining tokens || Multiple flows for different use cases
|-
| '''Mobile and Web Support''' || Less suited for mobile and web apps || Designed with mobile and web applications in mind
