Is Your Recovery Phrase That Important?

Definitely yes. Are your passwords important? Your credit card PIN? Email Accounts? Your recovery phrase is even more critical as it cannot be recovered if lost and cannot be stopped if it falls into other hands than yours.

For the reasons mentioned above, you can’t just write down your seed phrase on a sheet of paper! Of course, it should be in a firmly secured and protected place. That’s where the Cryptosteel capsule comes into play. In this Cryptosteel Capsule review, we’ll speak in-depth about the product, explaining why it really impressed us.

Cryptosteel Capsule is the premier backup tool for autonomous offline storage of valuable data without any third-party involvement. Because of the solid metal device, it can survive extreme conditions and work under nearly all circumstances. It’s also compatible with most secret sharing and key generation algorithms.


Here are Cryptosteel Capsule features that protect your seed phrase to the bone.


Impervious to plain water and highly resistant to acids and other substances, the Capsule’s 304 and 303 grades of stainless steel offer the optimal combination of strength and durability. At the same time, 316-grade steel and other alloys claim higher corrosion resistance in extreme-pH environments.


For the Capsule, the fire can burn even hotter and more prolonged with absolutely none of the warping that could put your data at risk. Unlike deliberate sabotage with a blowtorch, which burns 2-3 times hotter than most fires, a typical house fire will not distort a capsule.

Improved Security.

Passwords are protected, and not visible at first glance.

High Mobility.

Small, light, easy to hide and protect.

High Flexibility.

The capsule features adjustable separators, offers more capacity – 123 instead of 96 characters most other solutions provide – and comes with a full ASCII character set supporting random passwords with numbers and symbols. All of the characters are deeply stamped into the tiles to provide maximum longevity.

How to Use Cryptosteel Capsule to Secure Your Recovery Phrase?

1. Firstly, Cryptosteel Capsule and its parts.

2. Unscrew the capsule: Twist the cap to remove the core from the capsule.

3. Remove the informative ribbon.

4. Use character tiles to arrange your data: Choose the character tiles from the container. We recommend setting out each segment of your code in advance on a flat surface and then sliding them onto the core one by one. If you store a recovery seed phrase longer than 12 words, use only the first four characters of each word.

5. Use separators to segment information: You can use separators between words.

6. Slide tiles onto the core: After your data is set, slide the pierced tiles onto the core one at a time. This is the perfect time to double (or triple-check your work.

7. Place and fold the fastener to hold tiles: Just bend the tiny strap with your fingers > 90 degrees. Then put it on the core, and pull firmly to close it into place.

8. Finally, Screw the capsule back together.
