Unless you open your wallet in another person device and click remember me in the device and you logout from the device and unknown to you the person clicked remember password and the person login after you have logout. And go to the setting and see the seed phrase and copied it and transfer it to somewhere and later use it to hacked the wallet from another device if not nobody can Brute-force  wallet and see your seed phrase. Seed phrase is not a password that hackers can use trial and error method to get it. It is a combination of 12 words so it is impossible for them to do that.

Hackers use Brute-force on straight forward password and not even complicated ones.
