How to port out and get your transfer pin

When you create an account with Cape, you generate a 24-word passphrase on your device instead of a traditional username and password. This passphrase is based on BIP-39 (Bitcoin Improvement Proposal 39), a widely used standard for creating and managing cryptographic wallets in a user-friendly way. The passphrase is generated using specific algorithms that convert random numbers into a list of words selected from a standardized dictionary of 2,048 words.

Cape uses public key cryptography, also known as asymmetric cryptography, to secure your account. Your 24-word passphrase acts as a human-readable representation of a cryptographic seed used to generate your private and public keys.

• Private Key: Kept secret and stored locally and securely on your device. This key never leaves your device, so neither Cape's backend nor any other system ever has access to your private key.
• Public Key: Derived from the private key and used by Cape's systems to verify your identity.

Whenever you need to access your account or take an important action, such as replacing your phone or getting a new number, you use your 24-word passphrase. Entering this passphrase regenerates the cryptographic seed, and from that, your private and public keys. Cape's server verifies your public key with a digital-signature-based proof of ownership check. Only your on-device private key can generate a valid signature for your public key, ensuring that the person accessing the account is indeed you.

Troubleshooting:

 "Something went wrong with your account number"

Overview
When transferring (porting out) your Cape number to another carrier, the new carrier's system may display an error such as "Something went wrong with your account number." In most cases, this error originates from the receiving carrier's system and not from Cape. It can usually be resolved by adjusting how the account number and phone number are entered.

What you'll need to port out
When your new carrier asks for your account details, use the following:

• Account number: This is the same as your Cape phone number
• PIN / Transfer PIN: Found in the Cape app
• Phone number: Your Cape number

How to resolve the error
If you or the carrier's sales rep receive the "Something went wrong with your account number" error, try the following:

1. Re-enter the account number as your full phone number.
2. For the phone number field, add a "1" in front of the number.
   • Example: for 123-456-7890, enter 11234567890
3. Enter the PIN exactly
