How secure/uncrackable are Google Pixel 4 & 5's? Only 6 & 7 have TitanM2 chip.

I'm already aware of how long each of these models will keep getting graphene security updates.
Has Pixel 4 & 5 ever been cracked? I can get a google pixel 4a for $100. But a google pixel 6 is over $400. (I'm looking for cheapest model one i can get). -Thanks.

What exactly do you mean by "cracked"?

abcZ, merely bruteforce cracking the password.

Titan M2 and Tensor chips are part of what is called "Secure Element" and GrapheneOS developers have no control over it. In other words, all Pixel models running the same GrapheneOS version have close-to-equivalent level of security if "Secure Element" is not taken into consideration. If "Secure Element" is taken into consideration, then Pixel 6 and Pixel 7 phones should be more secure than their predecessors. Google specifically mentions Tensor core securing user keys and credentials - https://9to5google.com/2021/10/27/pixel-6-tensor-security-titan-m2/ .

OpenSource-Ghost, how crackable are the Google Pixel 4 & 5's? How long a password would they have to have for military grade technology to be unable to bruteforce crack it?
