I use another alternative operating system on my Fairphone 3/3+. Will this issue affect me as well?
Yes. Alternative operating systems all use the same fingerprint firmware as our official software, since there is no alternative or open source firmware available for Fairphone 3’s sensor. Therefore, in terms of fingerprint detection and spoofing security (reproducing someone else’s fingerprint), other systems will be as secure as our official one.
If you are referring to whether LineageOS, for example, now also classifies the fingerprint sensor as Class 2: No, it doesn’t. LineageOS has reverted the commit that would implement this security check:
Good news.
We all are aware of the Fingerprint lock feature issue in the official FairphoneOS Android 13 release and the cause for this.
I have discussed with the LineageOS team and they are fine to have the feature disabled. So yes, we will not be reverting this commit and fingerprint unlocking can be used on all 3rd party applications.
Thanks.
