Enabling Plugins in Electrum

1. Open Electrum and go to Tools → Plugins.
2. Internal plugins are listed in the dialog. Toggle the checkbox to enable or disable them.
3. External plugins can be imported from .zip files by clicking the Add button in the plugins dialog.
4. Some plugins (hardware wallets) are automatically enabled when you create or restore a hardware wallet.

First-time setup: When loading an external plugin for the first time, Electrum will ask you to set a plugin password. This password is independent of your wallet and can be reset if forgotten. To verify plugin authenticity on subsequent startups without re-entering the password, Electrum requires you to store a public key string with root permissions. The root permissions prevent malware from modifying the key.
