The verification code is used as a device recognition string when paring imKey and imToken. The verification code serves as a layer of security authorization to ensure safe access when pairing imKey with multiple imToken applications, preventing unauthorized devices or clients from connecting to your imKey.
During the initial pairing of ImToken and imKey, the verification code will be automatically displayed on the screen of the imKey. Users can conveniently input the displayed verification code on imToken. If there is a need to connect to multiple imToken clients, then the verification code should be safely kept and correctly filled in during the initial pairing, since imKey will only display the verification code during the initial pairing. This function ensures that imKey is not randomly paired with other imToken clients. Therefore, there is no need to worry when the imKey is lost, since pairing is not possible without the verification code.
