Hi,

can anyone describe to me, what the relationship between the 12 word seed in Electrum and the extended private key is?

If someone were to get the master private key, or the master public key PLUS one or more private keys, should I go for

Option A: simply add one word to the seed as a password, thus totally changing the master private key and have a secure wallet once again.

Or could an attacker calculate the seed from the master public key and thus trivially brute force the one additional word? Which would mean I should opt for

Option B: make a completely new seed.

Thanks in advance.
