Before accessing another PC remotely over the internet using AnyViewer, it's necessary to have a look at "Recipient" Settings for the PC that needs to be accessed. 

The default settings of Recipient

On the main interface of AnyViewer, go to Settings and choose "Recipient".  Then, you can see the default settings of  Recipient. 

Default Recipient

There are three options: Allow to accept remote control; Allow temporary security code; Set my security code.  The first two options are enabled by default. 
✔ Allow to accept remote control: allow this PC to receive a control request from another device and the request needs to be confirmed manually on this PC.
✔ Allow temporary security code: generate a temporary security code automatically and allow this PC to be controlled by inputting a temporary security code. You can send your partner the temporary security code for remote support.
✔ Set my security code: set the security code for this PC manually and allow this PC to be controlled at any time by inputting the security code. 

☞ Note: For differences between temporary security code and security code set manually, refer to All Things about Security Code in AnyViewer
