If someone gets the phrase, nothing will stop this person from getting the money, I believe. Because one can just go with the seed phrase to Electrum, and recover the wallet. So additional measures are not very helpful this way. It's possible to set a password, set a 2FA, etc., but I don't think it helps, ultimately. Moreover, if someone did make such measures unavoidable, it can lock one out of one's own wallet because of not having access to a phone with which the 2FA was set or forgetting the password. As for a fingerprint, not all devices allow this identification yet, so it can limit access to one's coins, but overall it might not be a bad idea. Then again, some here say fingerprint ID isn't as safe as it seems, so I'm not sure.
But not all are familiar with the seed phrases because it's only being used on cryptocurrencies but for finger print, it's being used anywhere and people are familiar with it. When they see that it only needs a fingerprint to access the wallet they can just wait for the target to fall asleep and then grab his finger to open the wallet.
A Fingerprint is easy for a crypto owner to access their accounts but it's also easy for the criminals to steal your wallet. For me I will still prefer the old way of accessing and recovering our wallets. It's not that hard but as long as you will keep your private keys on a place that you can remember for years.
