tip

  • CLion will automatically log you into your JetBrains Account if you're using ToolBox to install JetBrains products and already logged in there.

  • If you use two-factor authentication for your JetBrains Account, you can specify the generated app password instead of the primary JetBrains Account password.

Start the free trial

  • In the Licenses dialog that opens when you start CLion, select the Start trial option.

    Click Log in in the bottom-left corner. You will be redirected to the JetBrains Account website.

    Log in to JetBrains account to start trial version

    Log in to your JetBrains Account on the website and click the Start Trial button in the Licenses dialog to start your trial period.

    Start your trial version

Upon the expiration of the trial version, you need to buy and register a license to continue using CLion. A new trial period will be available for the next released version of CLion.

Activate CLion license

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

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

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

    If you don't have a JetBrains Account yet, use the Register button.

    Activate CLion license with a JB Account

    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.

    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.

Change the active user

  1. Select Help | Register from the main menu or click Options Menu | 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.

    Logging out to change the active user

Access to JetBrains Account: Troubleshooting

If you encounter problems when attempting to log in to your JetBrains Account, this may be due to one of the following reasons:

Log in with an authorization token

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.
