I thought a lot about using a decent random passphrase as unlock method for my profile but it seems so long to type everytime (even with the fingerprint, I'm experiencing an issue consisting of fingerprint not always showing when switching profiles so I have to type my code).

So I'm considering, instead of having a long passphrase as unlock method, to have a full random PIN code between 10 and 15 digits (not difficult to remember for me as I have a very, very good memory).

Do you think such pin code would be as efficient as a random passphrase ? Or >10 digits pin code is almost the same as 6 digits ?

Thanks

    IksNorTen If you're using a Google Pixel 6 or higher and you trust the secure element, a random 6-digit pin code is sufficient, there's currently no way to break the Titan M2.

    Soon, it will be possible to add a PIN code as a second fingerprint unlock factor to enable users to use a robust passphrase combined with a secondary PIN and fingerprint unlock for added convenience, in which case a PIN code of just 4 random digits will suffice, avoiding the need to trust the secure element that always ends up being broken at some point.

    I use a 14 digit pin. The pin input layout set to random and It works for me. It's not that I need this level of difficulty, I'm nobody special, just an average guy, its just something that comes easily to me, so I use it. The finger print sensor is a waste of time for me, I work with my hands, so my fingerprints can be altered hour by hour. Try bricklaying for 20 minutes and then use fingerprint recognition to get into your phone!

    Pin number above 6-8 has no use. You are depending on the secure element either way. An exploit of the element would render both a 6 and a 20 digit pin useless.
    If you plan on using a longer pin for added security, you should rather use a 100+ entropy password/passphrase to avoid depending on the element entirely.
