A cryptocurrency wallet's recovery phrase (seed phrase) is the sole key to restoring your wallet. Losing this phrase means you have no way to recover your assets, even if an exchange collapses. While there are cases where users successfully recovered approximately 6.5 ETH (a significant sum at the time), incidents of asset loss due to leaks or misplacement remain all too common. This article provides a neutral overview of recommended storage methods as of and highlights critical mistakes to avoid when storing your seed phrase.
What Is a Recovery Phrase?
A recovery phrase typically consists of 12 or 24 English words and serves as the foundational information used to generate a wallet's private keys. With this phrase, you can restore the same wallet on a different device or application. Conversely, if this phrase is exposed to a third party, they could potentially gain access to and seize control of your wallet.
Also known as a "seed phrase," the recovery phrase is the most critical piece of information for self-custody of cryptocurrencies. Unlike exchange accounts, wallet backups must be managed responsibly by you alone.
Basics of Secure Storage

Offline Physical Storage
The most fundamental method is to record your recovery phrase on paper or a metal plate and store it in a physically secure location, such as a safe or a safety deposit box. Since paper is vulnerable to fire and water damage, using highly durable metal plates (seed plates made of titanium or stainless steel) is also widely recommended.
Distributed Storage Across Multiple Locations
Instead of storing everything in one place, you can split the phrase and store the parts in multiple secure locations. However, if the splitting method is incorrect, restoration may become difficult, so sufficient understanding and testing beforehand are essential.
Using a Password Manager (For Advanced Users)
Another option is to encrypt and store the phrase in a password manager, though this carries the risk of the manager itself being compromised. If you choose this method, be sure to select a reputable service and always enable multi-factor authentication.
Where You Should Never Store Your Recovery Phrase
Storing in Plain Text on Digital Devices
Saving your recovery phrase directly in a smartphone notepad or a computer text file is extremely dangerous. Malware or hacking attempts can easily expose your phrase to unauthorized parties.
Storing on Cloud Services
Avoid storing your recovery phrase on cloud storage platforms like Google Drive or Dropbox. If your account is compromised, your phrase could be leaked. Similarly, taking and saving screenshots of your recovery phrase poses the same high risk.
Sending via Email or Social Media
Sending your recovery phrase through email or social media carries a very high risk of exposure to third parties. Even if you're sending it to yourself, there's still a chance it could be intercepted during transmission or leaked from servers.
Risks and Considerations
Managing recovery phrases involves risks of both loss and leakage. If lost, you will be unable to access your assets; if leaked, your assets could be stolen. Additionally, depending on the wallet type, the phrase format may differ, so please check the official documentation for the latest information.

Furthermore, regulations and tax systems regarding the trading and storage of crypto assets vary by country and region. For handling within Japan, we recommend referring to official information from the Financial Services Agency (FSA) or the National Tax Agency.
Summary
Secure management of your recovery phrase is essential for self-custody of cryptocurrencies. Prioritize offline storage using paper or metal plates, and avoid saving your phrase on digital devices or in the cloud. It is also crucial never to share your phrase with third parties and to regularly verify your storage setup.
