Help please recovering a wallet from a 17 word mnemonic phrase and other info 4 years ago I bought bitcoin and I have 
a 17 word mnemonic phrase
an identifier
a bitcoin address
and what I believe is a password

Does anyone know how I can access this bitcoin?
Do you remember where you created the wallet?
I assume it was a legacy wallet on blockchain.info, if so you can recover your ID and password here https://blockchain.info/wallet/forgot-password .
