To restore the wallet, the mnemonic, passphrase, password, etc. created when the wallet was first used are required. However, when the time comes to restore the wallet, the external storage medium on which the mnemonic, passphrase, password, etc. were recorded may have deteriorated over time and become unusable, making it impossible to restore the wallet. Be sure to consider the product specifications of the external storage media used to store important electronic data before using it.
Store important information with the expectation that the external storage media will deteriorate!
For example, when using USB memory devices, there are risks such as limitations on the number of times they can be rewritten and the volatilization of data when left unattended for long periods of time. When using external storage media, check the number of years of operation warranty and understand the characteristics of the product before using it properly.
