This is unfortunate situation. But if you keep using it in the device where the password was set, the password is not required to access to the memory card. However, it is required in the following situations:
- Try to remove the memory card password
- Insert the memory card to another device
- After a hard reset of the device (for example by typing *#7370# in your device)
- After the device software update with PC using Nokia Software Updater
When you forget the password but still want to use the memory card, try formatting it in your device. But after formatting, all data on the memory card is erased. Sometimes the password may be asked before formatting, then try to format it in PC.
Important notice! Write down your password and keep it in a safe place and backup your memory card data regularly.
