Works as expected. Can you add an option to have the widget on lock screen always show the number? (I know it’s not “secure” but saves me from logging in). Can you create it for Amazfit watches? Thanks

It’s been several years since 2FAS was rejected by PrivacyGuides due to a botched implementation of end-to-end-encryption in iCloud backups. The fact that this was botched in the first place is troubling enough, but even worse is that it took 3 years to improve it. How many people were left at risk using the backup while 2FAS took their time to fix it? I like the app, but I am not confident the 2FAS team know what they’re doing in terms of privacy. Check threads on PrivacyGuides for deep details. It’s quite disappointing. Anyway, 2FAS has claimed to have released a fix in 2026, but that to my knowledge hasn’t been audited externally, so I still haven’t enabled iCloud backups.
