What does QR activation image mean?
A QR activation image is a machine-readable representation of data used in a setup flow. It can encode a public address, but it can also contain a private device key, token or account link, so its privacy depends on the encoded content.

Crop the whole code or cover it solidly before sharing a screen. If inspection is necessary, use a trusted local decoder and review the destination before opening it.
