Make a SECURE Bundle.

Save 15% on a Blockplate PASSPHRASE by adding a Blockplate 12 or 24 to your cart.

DISCLAIMER: This is for BIP39 passphrases. This is an advance feature. A passphrase is different from your 12-24 word seed phrase. Do NOT purchase this if you do not fully understand the passphrase function. If you’re looking for our seed storage options, see Blockplate 12 and Blockplate 24.

BIP 39 Passphrase

Stores up to 100 characters(50 on front, 50 on back) and supports 95 printable ASCII characters (A-Z, a-z, 0-9,  !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~).

Fast, Easy, and Efficient

Blockplate PASSPHRASE works similarly to our standard center punch method with one minor caveat: Punching an additional hole for the type of character you're using. Learn more how it works.
