MacBook rejected correct password, required FileVault Key

I am writing to report a serious issue I experienced with my MacBook and to formally state that this situation was not caused by user error.

I have been using the same login password consistently for the past 2.5 years on my MacBook. The password was correct and unchanged. Despite this, my Mac suddenly stopped accepting the password and redirected me to a FileVault Recovery Key screen, making my system completely inaccessible.

At no point was I informed that my regular login password would become irrelevant or unusable due to a system or encryption state change. I did not forget my password, nor did I enter it incorrectly. The issue appears to be caused by a system-level FileVault or macOS security malfunction, not by any action or negligence on my part.

Additionally:

My Apple ID associated with this Mac is correct and unchanged.
I was successfully using the same password shortly before the lock occurred.
There was no warning, alert, or guidance provided prior to the system becoming inaccessible.
The system offered no viable recovery option except a FileVault Recovery Key that was never presented again after initial setup.

This experience resulted in a complete lockout from my own data, even though I had valid credentials. From a user’s perspective, this is extremely concerning, as it creates a false assumption that regular password access guarantees system recovery, which clearly is not the case.

I strongly believe this incident highlights a critical usability and communication flaw in the FileVault security flow. Users should be clearly warned about:

The permanent consequences of losing the recovery key
The fact that a correct password may still fail
The absence of Apple-side recovery even for verified owners

I request that this feedback be escalated and reviewed seriously, as this situation caused unnecessary data loss risk and significant disruption despite responsible and consistent usage.

Thank you for taking the time to review this feedback.

Sincerely,

Did you try your 24 character recovery key?

Do you have any backups of your computer or your important files? If so, while inconvenient, erasing the Mac & restoring from a backup should get you back in operation again. You should be able to use the "Erase All Content & Settings" option to quickly clean macOS so that you can begin restoring from a backup.

FYI, there are a lot more new ways to permanently lose access to the data stored on the internal SSD of the recent Macs due to all of the hardware, software, and security changes. People should always have frequent and regular backups of their computer and all external media (including the cloud) which includes important & unique data.

The more security that is implemented, the more likely a user will get locked out of things....this applies to your computer, phone, and even online accounts. It is a shame their are so many miscreants in the world trying to attack & steal peoples' data that we must such intense security measures enabled, but that is the world we live in today.

As for your valid complaints about Apple's presentation of security features and information.....sometimes it can be very lacking & even confusing. You can provide Apple with product feedback here:

Also, after you sort things out, you may want to consider creating a spare macOS admin user account which can be used in case you are unable to log into your main user account. This may give you one extra chance at access next time something goes wrong. I have seen a couple of cases where one user account may have had something go wrong and could be fixed by using another macOS admin user account...including being able to change that main user account's password. Also if something breaks between the main user account & Filevault, then the other admin user may be able to unlock Filevault and allow the main user to then log in after which that user & Filevault can be resynced.

This is a user forum, not Apple.

You’ll need to enter your key. You are instructor to write down the key and keep it in a safe place.

FileVault keys are typically 24 characters. The 28 characters are for your account recovery key. What is the exact message? Screenshots are helpful.

I do have a recovery key. The problem is that the system is now requesting a 28-character FileVault recovery key, while the key originally generated and provided to me is 24 characters long.

After the recent macOS 26 update, FileVault appears to have been automatically reconfigured or re-enabled without any explicit user notification, consent, or warning, resulting in a recovery mechanism that no longer matches the originally issued key. At no point during the update process was I informed that:

FileVault settings would change
A new or different recovery key format would be required
My existing recovery key could become invalid

Before the update, the Mac was functioning normally with the same password and Apple ID I have used for over 2.5 years. Immediately after, the password was rejected and the system redirected to a FileVault screen requiring a recovery key that does not correspond to the one Apple originally generated.

This is not a case of “not writing down the key.”

This is a system-level inconsistency caused by an OS update, where:

The login password stopped working
The recovery key format changed
No prior warning or regeneration prompt was provided

That is precisely the usability and communication failure I am reporting.

I understand this is a user forum, but dismissing the issue as user error is inaccurate when the recovery credentials themselves no longer align due to an Apple-initiated system change.
