By default, IntelliJ IDEA saves your passwords for version control repositories, databases, and other protected resources. Configure the way the passwords are saved:
In native Keychain
Use the native keychain app.
This option is not available for Windows. macOS uses Keychain Access. For Linux, it depends on the desktop environment and available apps: if you have both GNOME Keyring and KWallet, IntelliJ IDEA will use GNOME Keyring for compatibility reasons because KWallet was not supported in previous versions.
Use the KeePass password manager.
Do not save, forget passwords after restart
Do not remember any passwords and always prompt for credentials to protected resources.
