How to backup the wallet if the wallet mnemonic words not recorded? Thanks

studyres · August 11, 2019, 1:52am

When I created the wallet I did not write the mnemonic words because I thought I can find it later via a command line, but then I could not find such a command.

Is there any way to get the mnemonic words again? or directly backup the full wallet to a disk file? like the BTC wallet.

Thanks.

You can use the sdks to do this if you know the wallet name and password:

Edit 2021-01-10: old links were broken - replacing them with new links for Python and Go:

# Example: backing up a wallet with mnemonic

import tokens
from algosdk import kmd, mnemonic
from algosdk.wallet import Wallet

# create a kmd client
kcl = kmd.KMDClient(tokens.kmd_token, tokens.kmd_address)

# create a wallet object
wallet = Wallet("unencrypted-default-wallet", "", kcl)

# get the wallet's master derivation key
mdk = wallet.export_master_derivation_key()
print("Master Derivation Key:", mdk)

# get the backup phrase
backup = mnemonic.from_master_derivation_key(mdk)
print("Wallet backup phrase:", backup)

For the sake of completeness, here were the old links:

Thank you. I am going try it.

I’d be very careful with a wallet you can’t recover, meaning that trying to do the minimum and safest actions with it since playing with code may be too risky.

I’d consider creating a new wallet (carefully saving the mnemonic) and simply transfer to the new one. Then, if you want, try to recover it.
