The same word appears more than once in my recovery words(mnemonic code). Is this normal?
While writing down your recovery words (mnemonic code), you may find that the same word appears more than once.
This is not a wallet setup error but a normal result under the BIP39 standard.
[Why the same word can appear more than once]
The recovery words used in DCENT wallets (DCENT X, Biometric Wallet, DCENT S Card Wallet) are generated in the secure chip inside the device (card) by randomly selecting 24 words from the list of 2,048 English words defined by the BIP39 technical standard.
Because the words are selected randomly, the same word can be included more than once, although the probability is very low.
(e.g., the 1st word is "apple" and the 20th word is also "apple")
[Is there a security problem?]
- The combination of all 24 words works as a single master key.
- Even if some words are repeated, there is virtually no chance that another user has the exact same combination of recovery words.
- Therefore, repeated words are not a security problem, and if you wrote down all 24 words in the correct order and spelling, you can safely use them as they are.
[Precautions for managing recovery words]
- Do not store them digitally, such as by taking photos or saving them to the cloud, messengers, or memo apps.
- Write down all 24 words in order on paper. For the Biometric Wallet, you can use the included Recovery Sheet.
- Keep them in a place safe from water, fire, and theft.
- If you lose or leak your recovery words, DCENT cannot help you recover them.
