If you notice that your own personal email is displayed in recordings, it may seem concerning but there is a simple explanation.
Your password manager or other form auto-fill tool may also fill out those same fields in Mouseflow recordings.
This happens because the recordings aren't a typical video playback but a recreation of the HTML from your page. This causes the auto-fill tool to recognize the form fields in the recording and fill them out.
Can I hide it?
You can prevent this issue by temporarily disabling the password manager or opening the recording in another browser or an incognito window.
