Even if the system allows you to set the password using € , you are taking a massive risk. The system might record the password using one character encoding method, but attempt to unlock it using a different one during boot.

You can use the euro symbol in an (Windows, macOS, Linux) if the input method supports UTF-8. But for an SSD hardware password (often called ATA Security, OPAL, or DriveLock password entered before the OS boots), the character set is radically limited — usually to ASCII 32–126 (no Unicode, no €).

If you really want a strong SSD password, use a long random string of ASCII printable characters. Save the euro symbol for your bank PIN or your encrypted disk volume inside the OS — where Unicode is fully supported.

However, an SSD password (often called an or OPAL Password ) is handled by the drive's firmware before your operating system loads. At this stage, the computer is in a limited state known as a "Pre-Boot Environment."

In the Pre-Boot environment, the system often loads a generic US English keyboard driver by default. If your password relies on a specific regional layout (like German QWERTZ or French AZERTY) to produce the € , the pre-boot environment might be "blind" to that combination. It sees the key press but translates it incorrectly, causing your password to fail every time you try to unlock the drive.

| Device/BIOS | € symbol behavior | |------------------|-------------------| | Dell Latitude (pre-2020) | Not allowed — key produces nothing | | Lenovo ThinkPad (UEFI) | Shows ? or blocks password set | | Samsung SSD (PSID revert) | Only ASCII 32–126 | | Crucial MX500 (OPAL) | Works only in OS tools, not pre-boot |

To ensure maximum compatibility and safety, follow these rules for hardware-level SSD passwords:

Hardware passwords are often stored as a simple . Standard characters (A-Z, 0-9) take up 1 byte each.

The primary reason you cannot use the € symbol comes down to the password is being processed.

When you set a password for your operating system (like Windows or macOS), the OS loads a sophisticated environment that knows your keyboard layout, language settings, and thousands of special characters.
