Go-Guardian is a golang library that provides a simple, clean, and idiomatic way to create powerful modern API and web authentication.

Go-Guardian sole purpose is to authenticate requests, which it does through an extensible set of authentication methods known as strategies.
Go-Guardian does not mount routes or assume any particular database schema, which maximizes flexibility and allows decisions to be made by the developer.
The API is simple: you provide go-guardian a request to authenticate, and go-guardian invoke strategies to authenticate end-user request.
Strategies provide callbacks for controlling what occurs when authentication should succeeds or fails.

Using go-guardian is easy. First, use go get to install the latest version of the library.

go get github.com/shaj13/go-guardian/v2

Next, include go-guardian in your application:

import "github.com/shaj13/go-guardian/v2"

When building a modern application, you don't want to implement authentication module from scratch;
you want to focus on building awesome software. go-guardian is here to help with that.

Here are a few bullet point reasons you might like to try it out:

• provides simple, clean, and idiomatic API.
• provides top trends and traditional authentication methods.
• provides two-factor authentication and one-time password as defined in RFC-4226 and RFC-6238
• provides a mechanism to customize strategies, even enables writing a custom strategy

JWT, Opaque, and oauth2 packages provide early access to advanced or experimental functionality to get community feedback. Their APIs and functionality may be subject to breaking changes in future releases.

• JWT
• Opaque(server-side consistent tokens)
• Oauth2-JWT
• Oauth2-Introspection
• Oauth2-OpenID-userinfo
• OpenID-IDToken
• kubernetes (Token Review)
• 2FA
• Certificate-Based
• Bearer-Token
• Static-Token
• LDAP
• Basic
• Digest
• Union
