Apple may finally bring Touch ID to the Apple Watch. Internal code spotted by Macworld and confirmed by MacRumors shows Apple experimenting with biometric authentication for the 2026 lineup. The code references “AppleMesa,” Apple’s codename for Touch ID, suggesting that prototype models already include the technology in some form.
It’s unclear how Touch ID would be implemented. Apple could place the sensor under the display, similar to some Android phones, or integrate it into the side button. If launched, Touch ID would improve security and make features like Apple Pay more convenient by reducing reliance on passcodes.
The discovery points to three models under testing:
- N237: Apple Watch Series 12
- N238: Apple Watch Series 12 with cellular
- N240: Apple Watch Ultra 4
These models will also include an all-new CPU labeled T8320. Current S9, S10, and upcoming S11 chips all share the identifier T8310, meaning the 2026 watches could deliver the first true S-series upgrade in years.
Beyond Touch ID and a faster processor, the code suggests a major shift. The 2026 lineup is internally identified as “Watch8.” By contrast, the Series 9, 10, and 11 were all tagged as “Watch7.” This signals a larger redesign is on the way. DigiTimes recently reported that Apple is preparing significant design changes for the next-generation Apple Watch, adding weight to these findings.
Apple could still change course and remove Touch ID before release. However, the presence of code references shows that biometric authentication is under serious consideration. If these features arrive as planned, the Apple Watch Series 12 and Ultra 4 may deliver the most meaningful updates in years.
