  • PIN adds protection beyond TPM alone

    “A vulnerability can't leak your key if the TPM doesn't know the entire key and relies on the user to supply the missing parts of the key in the form of a PIN.”

    Comment from 2 Jul 2026 in “Since Linux 6.9, LUKS suspend stopped wiping disk-encryption keys from memory”

    “A vulnerability can't leak your key if the TPM doesn't know the entire key and relies on the user to supply the missing parts”

    Comment from 2 Jul 2026 in “Since Linux 6.9, LUKS suspend stopped wiping disk-encryption keys from memory”

    “If you're at all serious about security and not user convenience, you deploy BitLocker with a PIN instead of TPM only.”

    Comment from 2 Jul 2026 in “Since Linux 6.9, LUKS suspend stopped wiping disk-encryption keys from memory”
  • Good default for most users

    “the default Secure Boot BitLocker configuration, for all its architectural tradeoffs, can probably be credited for an enormous amount of data loss mitigation”

    Comment from 2 Jul 2026 in “Since Linux 6.9, LUKS suspend stopped wiping disk-encryption keys from memory”

    “It's certainly a reasonable default. People lose or have their laptops stolen much more often than they get targeted by their governments.”

    Comment from 23 Jan 2026 in “Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops”

    “It's a fairly reasonable default setting for average users who simply want their data protected from theft.”

    Comment from 24 Jan 2026 in “Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops”
  • Protects data when laptops are stolen

    “It protects their data in the event that someone steals the laptop, but still allows them to recover their own data later from the hard drive.”

    Comment from 23 Jan 2026 in “Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops”

    “Does the encryption keep the user's data safe if the device is lost or stolen? Yes? Then it fulfills its main purpose.”

    Comment from 15 Jun 2026 in “Windows 11 users are tired of MS account requirements creeping into everything”

    “It's a fairly reasonable default setting for average users who simply want their data protected from theft.”

    Comment from 24 Jan 2026 in “Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops”
  • Easy to set up and use

    “It's a few clicks to choose to re-key and not have the key saved to your Microsoft account.”

    Comment from 24 Jan 2026 in “MS confirms it will give the FBI your Windows PC data encryption key if asked”

    “the nice thing about Bitlocker is that you don't need to put in your key 99% of the time”

    Comment from 24 Jan 2026 in “Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops”

    “That's something that even your Grandma can do, as opposed to installing VeraCrypt”

What people warn about

Each mark is one comment

  • Microsoft holds keys, accessible to governments

    “Microsoft cares so little about privacy and security that they would do it just to end the help customers who lose their key support tickets”

    Comment from 23 Jan 2026 in “Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops”

    “There is reasonable suspicion, some might argue evidence, that Microsoft voluntarily cooperated with U.S. Intelligence Community”

    Comment from 24 Jan 2026 in “MS confirms it will give the FBI your Windows PC data encryption key if asked”

    “Companies know that putting themselves in a position where they can betray their users, means they will be forced to do so.”

    Comment from 24 Jan 2026 in “Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops”
  • Suspected backdoor

    “Bitlocker by default (although there is a convenient backdoor for high-paying customers”

    Comment from 25 Nov 2025 in “Google's new 'Aluminium OS' project brings Android to PC”

    “while bitlocker may be backdoored in the same way, it is at least maintained”

    Comment from 24 Jan 2026 in “Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops”

    “It seems undeniably a backdoor, why on earth would a very specific folder/file name and a specific boot combination just "magically" open up an encrypted drive.”

    Comment from 14 May 2026 in “Microsoft BitLocker – YellowKey zero-day exploit”
  • Hard to configure more securely

    “It's straightforward to configure BitLocker disk encryption to be more secure, but it creates enormous headaches for admins, so they don't do it.”

    Comment from 14 May 2026 in “Microsoft BitLocker – YellowKey zero-day exploit”

    “I've always found it silly that Microsoft's default BitLocker implementation doesn't make it easy to do the obvious thing”
