For example, if you want to push your snap to the Snap Store, you need to login on the command line. The process relies on the internal login mechanism built into Snapcraft. A preview functionality for a new Web-based authentication flow is available as an experimental feature in Snapcraft since release 4.6. This allows you to complete the login process in a simple, secure manner using the browser, and extends the macaroon-based authentication currently in use. # Get started To try the experimental login feature, make sure you have the relevant release of Snapcraft installed. The easiest way is to refresh Snapcraft from the *edge* channel. Then, on the command line, your login procedure will look like this: ``` snapcraft login --experimental-login Opening an authorization web page in your browser. If it does not open, please open this URL: https://api.jujucharms.com/identity/login?did=c0cf2e16bc2244001945a6b3fe6d56c4e35a8401a3678ecff9fce89ef6cd2583 ``` Snapcraft should forward the query to your default browser and open the login page, where you can then identify. This could be Ubuntu SSO, optional MFA, and any other methods that you would use. Once you complete the authentication, you will see another line printed on the command line. ``` Login successful. ``` If you do not wish to use the experimental login feature anymore, you first need to logout and have the credentials cleared, and then, you can go back to the standard login process. ``` snapcraft logout Credentials cleared. ``` In scenarios where the Web-based access may be restricted, developers can export the credentials with the *export-login [file]* command, and then use them on other systems by passing on the *–with creds-file* option to snapcraft login. # Summary The experimental login allows Snapcraft users to authenticate through a Web-based flow. This provides extensibility and security that goes beyond the classic command-line login. However, in some scenarios, the Web-based method may not be ideal or available, which is why Snapcraft also allows the export of credentials, offering additional flexibility to the users. If you’d like to test the feature and provide feedback, please take Snapcraft for a spin, join [our forum](https://forum.snapcraft.io/), and let us know your findings.
