I got myself a wallet back in 2015. I put bitcoins in there and forgot about them. Of course, because of the course, I remembered about this wallet, but I forgot the password. I have a wallet backup, but I can't do anything. Is it possible to remove the password from the wallet? please help me
To recover your wallet you'll need to crack the password on it, since the password is used to encrypt the wallet file.
You can use a program like https://github.com/gurnec/btcrecover to attempt to crack it. If you have any idea of what the password might have been, you can supply them as hints to the program to have a better chance of cracking it. If the password was very long and you cannot provide a hint, you may be SOL until you remember it.
