Hi,

A friend wants to degoogle his phone, so I suggested the OS I'm currently using. The one we can't talk about... He wants a small/compact phone, so I suggested pixel 4a (not buying second hand though), but I'm afraid that planned obsolescence may kill the phone rather soon. What's your opinion?

Cheers and thank you for your help,

Devices that incorporate a TPM can create cryptographic keys and encrypt them, so that the keys can only be decrypted by the TPM. This process, often called "wrapping" or "binding" a key, can help protect the key from disclosure.

This is how cell phones and windows hello justify short pins, the pin goes into a rate limited TPM that then discloses a larger key to decrypt the actual secret.

Do you need me to link to the vulnerabilities of TPMs? They do not provide physical security.

Does this mean your also against yubikeys?

Hardware keys can be used well to increase your secuirty (U2F MFA) or used to increase convienence and reduce security (passwordless auth)

It depends how the tool is used.
