Control whether Siri works when locked
Quick answer
To stop Siri answering on a locked device, open Settings > Apple Intelligence & Siri and turn off "Allow Siri When Locked." Siri then requires unlocking before it acts, which is more private but less convenient. Leave it on for hands-free use; turn it off if others can reach your device.
Say this
“Hey Siri”
How it works
- 01Open Settings > Apple Intelligence & Siri
- 02Find "Allow Siri When Locked"
- 03Turn it off for more privacy, on for convenience

If Siri doesn't get it
Even with it on, some sensitive actions still require unlocking. Turning it off is the stronger privacy choice if your device is often within others' reach.
