Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.

Informations about the package hmac-authentication

FormatD.HmacAuthentication

This package adds an authentication provider for authenticating a flow account using a token with a configurable timeout. Authentication is done by passing username, timestamp and a hmac. For generating this token the package contains some viewhelpers and a Service.

Keep in mind: The token is usable multiple times and does not invalidate after usage. Only after a timeout.

Configure the Authentication Provider

In addition to your usual PersistedUsernamePasswordProvider you have to add a second UsernameHmacTimestampProvider provider to the configuration. Set the providerOption "mainAuthenticationProviderName" to the name of your PersistedUsernamePasswordProvider so that only the accounts of this provider can use the magic links.

Multiple AuthenticationProvider

To be able to use different AuthenticationProvider you have to add them to the allowedAuthenticationProviders configuration and pass the AuthenticationProviderName as the second parameter.

Authentication on button click:

Authentication with a link (not encouraged):

Be Aware!

This is a very dangerous way to do authentication as the login-link is tracked for example in server logfiles or cached in proxies. Setting the timeout as low as possible is a must. Always prefer the submit button solution mentioned above.

OK, let me do this anyway

There are two ways how to generate a authentication link: Use one of the ViewHelpers...

...or use the hmacService directly in your code:

Using only AuthToken:

If you want to use the authToken in your code (for example to authenticate something else) just use the service class
