Find the blockchain key file
If you downloaded a blockchain key file, try to find the file – usually, people download it either to their Download or Desktop folder. By default, the filename looks similar to this: CargoX – Blockchain key – Your Name – 0x94ffEB1b2277645f1022DcdD3B3819F974a3e96E.json, where the first part includes your first and last name, and the last part is your public blockchain address (which you can find by opening the gear icon (⚙) | Blockchain keys).
Find the saved blockchain key text
If at the time of creating the blockchain key you were unable to download the file, you might have decided to copy your blockchain key text to the clipboard. You would probably have saved it in a document on your computer. Try to remember where and when, and maybe you can find it. The blockchain key text is represented by 521 characters of text (without any spaces or split lines).
Try to the remember the blockchain key password
If you have the above blockchain key file or blockchain key text, but cannot remember the decryption password for the blockchain key: when you were asked to select the encryption password, we suggested that you do not repeat the same password that you used to sign in (but some users do so anyhow). Also, we request that the password be at least 8 characters long, and suggest that it include letters, numbers, and special characters.
