OpenID is a safe, faster and easier way to log in to web sites.

OAuth logo OAuth

OAuth is an open standard for authorization. It allows users to share their private resources (e.g.

OpenID features and specs

  • Single Sign-On
    OpenID allows users to log into multiple websites using a single set of credentials, simplifying the login process and reducing password fatigue.
  • Decentralized Authentication
    OpenID operates in a decentralized manner, meaning users can choose their identity providers, giving them more control over their online identity.
  • Improved User Experience
    By reducing the number of times users need to enter login information, OpenID can streamline the user experience across different platforms.
  • Enhanced Privacy
    OpenID allows users to manage their identity, providing them with the option to share only necessary information with websites.
  • Increased Security through Reduced Password Usage
    With fewer passwords to remember and enter, users can focus on creating stronger passwords for their OpenID accounts, potentially increasing overall security.

Possible disadvantages of OpenID

  • Reliance on Identity Provider
    Users depend heavily on their chosen OpenID provider. If the provider experiences downtime or a security breach, user's ability to log in to various services can be impacted.
  • Complexity in Implementation
    Implementing OpenID can be complex and requires significant development resources, which might be a barrier for smaller websites or developers.
  • Potential Privacy Concerns
    Although OpenID enhances privacy, it also puts pressure on identity providers to manage and protect user data adequately. Any data mishandling can affect user privacy.
  • Fragmentation of Standards
    The existence of multiple identity standards and specifications can create confusion and compatibility issues, leading to a fragmented user experience.
  • Dependent on Internet Access
    Like many online authentication methods, OpenID requires constant internet access, which can be a limitation in regions with unstable internet connectivity.

OAuth features and specs

  • Delegated Authorization
    OAuth allows users to grant applications limited access to their resources without sharing their credentials, enhancing security and user convenience.
  • Third-Party Integration
    Facilitates seamless integration with third-party services by allowing applications to access user data across different platforms securely.
  • Granular Access Control
    Supports fine-grained permissions, enabling users to specify exactly what resources an application can access and for how long.
  • Enhanced Security
    By allowing applications to access data without exposing user credentials, OAuth reduces the risk of password theft and other security breaches.
  • User Experience
    Improves user experience by allowing single sign-on and reducing the need for creating and remembering multiple usernames and passwords.

Possible disadvantages of OAuth

  • Complexity
    Implementing OAuth can be complex and resource-intensive, requiring careful handling of authorization codes, tokens, and various flows.
  • Security Risks
    If not implemented correctly, OAuth can introduce vulnerabilities such as token interception, token leakage, or insufficient token expiration time handling.
  • Evolving Standards
    OAuth standards and best practices evolve over time, which can require ongoing maintenance and updates to ensure that implementations remain secure and compliant.
  • User Consent Fatigue
    Frequent consent requests for different applications and permissions can lead to user fatigue, potentially causing users to ignore important security warnings.
  • Dependency on Third-Party Services
    Relying on OAuth providers for authentication can be challenging as service outages or changes to provider APIs might disrupt the dependent applications.

  • Bluesky partners with Namecheap to power domains as usernames
    Certainly _buying_ domain names to be your identity is new, but OpenID[1] was doing basically that 15 years ago. Add a few meta tags to your website homepage, use that homepage as your "identity" to log in to websites, and they'd up your configured identity provider to do the login & request name/email/whatever else.
