- for example you should know how long it was,
- what type of characters you used (upper case, lower case, symbols)
- it helps if you have a list of possible words you used in your password (e.g. Bitcoinpower100)
- generally anything that narrows that the list of possible passwords to check.
then you can use a tool like this: https://github.com/gurnec/btcrecover
I tried, I'm confused about a few steps or they not working so I'm not sure how to proceed.
if you are finding it hard to use that open source tool then there are other options/services you can use that can help you with recovering your wallet.
for example: https://walletrecoveryservices.com/
please note that i have never used this, so i don't know how trusted it is.
