14 October

Your Zoom meetings are not end-to-end encrypted by default, and Zoom's support documentation reads that for these meetings the encryption keys are generated and managed by Zoom's servers (checked on 10 October 2026). On 14 October 2020, Zoom announced that end-to-end encryption would be available as a technical preview from the following week, to free and paid users around the world. The announcement reads that with it turned on, the keys are generated by the participants' devices, and Zoom's servers only relay data without obtaining the keys needed to decrypt the meeting. According to Zoom's current documentation, turning on end-to-end encryption disables joining by telephone, the web app, cloud recording, live transcription and AI features, and the documentation recommends using it only for meetings that need extra protection. A host first turns on the "Allow use of end-to-end encryption" setting in the Zoom web portal and then chooses end-to-end encryption when scheduling a meeting, and hosts on free accounts must first verify a phone number by SMS.
