# Register IntelliJ IDEA You can evaluate IntelliJ IDEA Ultimate free of charge for up to 30 days. IntelliJ IDEA offers the following activation options: * [Free 30-day trial](#activation-options): a 30-day trial to explore all IDE features. * [Paid license](#activate-license) — a paid subscription for commercial use. * [Special options](https://www.jetbrains.com.cn/en-us/idea/buy/?section=discounts&billing=yearlynts): free access programs for students, teachers, and other eligible users. ## Trial and subscription When you start IntelliJ IDEA for the first time, you will be automatically granted a free 30-day trial. You can check the remaining number of days, by clicking Trial in the right upper corner of your IDE. If a trial period ends or your subscription expires, you will still have access to IntelliJ IDEA with a free feature set. After the trial version expires, you need to buy and register a commercial license to continue using the Ultimate feature set. A new trial period will be available for the next major version of IntelliJ IDEA.

License server: Register using the [Floating License Server](https://www.jetbrains.com.cn/en-us/help/license_server/Activating_license.html) or [License Vault](https://www.jetbrains.com.cn/en-us/help/license-vault-cloud/Activating_a_license.html#to-activate-a-license). ![Activate IntelliJ IDEA license with a license server](https://resources.jetbrains.com.cn/help/img/idea/2026.2/ij_activate_license_server.png) When performing a silent installation or managing IntelliJ IDEA 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](tuning-the-ide.html#configure-jvm-options). > **Tip:** > IntelliJ IDEA 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](tuning-the-ide.html#configure-jvm-options). 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`. ## Activation with JetBrains Account [JetBrains Account](https://account.jetbrains.com/login) is a convenient option to manage your licenses .

If there are no ports available, IntelliJ IDEA will suggest [logging in with an authorization token](#auth_token_eap_login). ### Unable to open JetBrains Account in your browser When you click Log in to JetBrains Account, IntelliJ IDEA redirects you to the JetBrains Account website. If your system browser does not start, use the Troubles? emergency button. IntelliJ IDEA will suggest [logging in with an authorization token](#auth_token_eap_login). Trial: ![The Troubles button in the Login dialog](https://resources.jetbrains.com.cn/help/img/idea/2026.2/ij_troubles_button_trial_login.png) EAP: ![The Troubles button in the Login dialog](https://resources.jetbrains.com.cn/help/img/idea/2026.2/ij_troubles_button_login.png) ### No access to JetBrains Account The login process requires access to the JetBrains Account website. IntelliJ IDEA automatically redirects you to the website or lets you log in with an authorization token. If both options do not work and you cannot access the website, contact your system administrator. Otherwise, it will not be possible for you to log in and start using IntelliJ IDEA. Procedure: Log in with an authorization token An authorization token is a way to log in to your JetBrains Account if your system does not allow for redirection from the IDE directly, for example, due to your company's security policy. IntelliJ IDEA 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. ![Copy the link to get an authorization token](https://resources.jetbrains.com.cn/help/img/idea/2026.2/ij_EAP_auth_token_login.png) 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 have successfully logged in, you can start using IntelliJ IDEA.
