alt Hacker News> On GrapheneOS, for privacy and convenience, it's best to use a long random passphrase
Why do you call out just one OS? It's a good idea for any OS.

Yes, in fact on GrapheneOS it's less necessary and it's only necessary if you don't want to rely on the secure element rate limiting.
GrapheneOS allows using a passphrase with more convenience because of the fingerprint plus second factor pin (I don't think you can just have a pin as a secondary unlock). You don't need to enter the passphrase every time you unlock with this setup, only when first starting up.

Because apart of the IOS, according to GrayKey and Cellebrite, GrapheneOS on Pixels is the only phone where it even makes sense (realistically).
This seems specific to GrapheneOS (unique as far as I know though I'd be happy to learn otherwise) where you could set a very long first unlock passphrase and have a shorter less cumbersome fingerprint plus pin option for subsequent unlocks. I wouldn't want to have to enter a long passphrase every time I unlock but once a day isn't so bad.
