Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

The difference is one stays local on your phone in a tpm only accessible from that device while the other is stored on some third party platform by a vendor you have never heard of with no information around security controls.
FaceID information is stored locally. You have to remember that FaceID isn't just a picture - it's a 3D depth scan using LIDAR. If every phone transmitted that information to Apple whenever phones were unlocked it would consume an absurd amount of data and thus money.

On a device with internet connection.
That has been audited by third parties around the world. I detest Apple's business practices, and even I know this ain't it chief.
Tell me you don’t understand technology without saying you don’t understand technology. Biometrics don’t leave Apple devices. Proof? Go get an old touch iPhone and set up a fingerprint and then try to use that to log in to a MacBook with Touch ID.
You can educate him without being insulting.
You are right, sorry about that. Just tired of people spreading bullshit and then by the time the truth gets said the lies have gone halfway around the world. People need to verify stuff before posting their every thought and whim.
I understand, thanks for being a sport. And I agree with you, we are overwhelmed with rumors, lies, and propaganda all the time so it's hard to stick to facts. In the case of op here, they were just trying to share an idea they had, and I've been in their position many times when I sounded like an ignorant schmuck when I just wanted to express a thought i had.
Or maybe better if op could spend 5 minutes to do their research before posting inaccurate claims.
tbf the same could be said about tyler
Probably he or she is simplifying the explanation because shared biometrics login doesn’t necessarily indicate that biometrics is stored locally.
But it’s true that no cloud nor third party involved in storing biometrics information.

how do you know?
my point is there is no way to know that. you can believe things, but that may or may not be the case.
That what apple says.
No body can confirm without reviewing iOS source code.
Edit: spelling correction
then I have a bridge to sell you. you just need to register on our website. register to the raffle too with your address and phone number and you may win the bridge for free, but don't worry we value your privacy.
that's what I say. surely it's all honest and true. you will have to believe us, because nobody can confirm it.
how ironic. that's not a proof at all. it not being usable on your other devices does not mean it is not uploaded. it just means the data is not synced to other devices for this specific purpose. we simply don't and cannot know whether it is uploaded anywhere.
You are right, it’s not proof! I was waiting for someone like you to say so, so I could point out that this has been tested numerous times by researchers and it does stay on device and is secure, that’s literally the entire point of a TPM.
