1. Select Help | Register from the main menu or click | Manage License on the Welcome screen to open the Licenses dialog.

2. Choose how you want to register CLion or a plugin that requires a license:

   JetBrains Account

   Activation code

   License server

   Log in to your JetBrains Account and get licenses that you have purchased.

   If you don't have a JetBrains Account yet, click Register.

   

   CLion automatically shows the list of your licenses and their details like expiration date and identifier. Click Activate to start using your license.

   If your license is not shown on the list, click Refresh license list.

   Provide an activation code and click Activate.

   

   When purchasing a product license, you receive a code for its offline activation. You can always download available activation codes from your JetBrains Account.

   Register using the Floating License Server or License Vault.

   

   When performing a silent installation or managing CLion installations on multiple machines, you can set the JETBRAINS_LICENSE_SERVER environment variable to point to the URL of the Floating License Server or License Vault.

   Alternatively, you can set the URL of the Floating License Server or License Vault by adding the -DJETBRAINS_LICENSE_SERVER JVM option.

   tip

   CLion detects the system proxy URL during initial startup and uses it for connecting to the JetBrains Account, Floating License Server, and License Vault. To override the URL of the system proxy, add the -Djba.http.proxy JVM option. Specify the proxy URL as the host address and optional port number: proxy-host[:proxy-port]. For example: -Djba.http.proxy=http://my-proxy.com:4321.

   If you want to disable proxy detection entirely and always connect directly, set the property to -Djba.http.proxy=direct.

1. Select Help | Register from the main menu or click | Manage License on the Welcome screen to open the Licenses dialog.

2. Click your name in the bottom left corner of the dialog and select Log Out.

   

   After logging out, you can log in using another JetBrains Account.

An authorization token is a way to log in to your JetBrains Account if your system doesn't allow for redirection from the IDE directly, for example, due to your company's security policy. CLion recognizes when redirection to the JetBrains Account website is impossible. It enables you to copy a link to generate an authorization token manually.

1. Click Copy link and open the copied link in your browser.

2. Log in to your JetBrains Account to generate an authorization token. After that, copy the token, paste it to the IDE authorization token field and click Check token. Once you've successfully logged in, you can start using CLion.
