You can set up your TeamViewer (Classic) temporarily saving connection passwords to make your workflow easier when connecting multiple times to a specific device when there is no one on the remote device, who could provide you with a changing random password.
📌 Note: Please keep in mind that there is an automated clearance of the cached password from memory after 5 minutes.
This article applies to all TeamViewer (Classic) users.
You can set up this setting in the TeamViewer (Classic) options.
Click the Gear icon (⚙) in the upper right corner of the TeamViewer (Classic) application and navigate to Advanced ➜ Advanced settings for connections to other computers ➜ Temporarily save connection passwords. Click the checkbox to activate and then OK to save.
