I forgot the password from wallet.dat 18.2 BTC

If you have lost your wallet password then it's like curtains for your coins. Try to recover with your seed, if you have that with you. Just few small things which we always ignore at the time of installing wallet can save us later from big troubles.

This is a little bit unusual, owning a huge of amount of btc and he forgot password because usually when you own big amount of btc you must have a duplicate of your keys or password. If he just keeps the seed he has a big chance of recovering his wallet. An owner of a wallet should makes other ways to remember it to recover the wallet.

Is there a way to determine the number of characters in the wallet password?  I haven't used mine since April 2018 and for some reason the password I remember using isn't working.  I installed the btcrecovery in python and have tried a few lists of possible variations of my password up to 109k possibilities, but still nada.  If I knew how many characters it was, it would help a lot for making my password lists.  And ideas?  It's very important, of course.  I don't think anyone could have messed with it because I had the wallet.dat file backed up in a rar stored away safely.  I tried two completely different backups of the wallet file.
