A simple Alexa command exposed my husband's sordid affair in graphic detail: Cheaters use 'sneak mode' to cover their tracks at home... but you can still uncover their hidden evidence

'I found out because I bought a new Amazon Alexa and while setting it up realized this is linked via our family prime account,' the woman shared on Reddit. 'Found in history, 'Alexa play beautiful love songs,' followed by the sound of them having sex.' To find such recordings saved to an Amazon Alexa, open the Alexa app, tap More, go to Alexa Privacy, then select Review Voice History to see recordings by date or device. Users can play back clips, delete individual recordings or delete their entire voice history. If you own a Google Home, open the Google Home app and tap Activity to review recent home events, including camera, doorbell and device activity. To check Assistant recordings, go to your Google Account activity controls and review or delete Google Assistant activity.
