this would not be possible because assuming imgflip has standard security features it stores the passwords in a secure database. but the passwords are probably encrypted with keys. to decrypt the passwords you would need 2 keys one of which is the public key and another which is the private key. finding the public is pretty easy however the problem is with the private key. to find the private key you would need access to the server and all its contents. keep in mind that you cant access the server from the devtools. once you have both the keys you can then decrypt the passwords and get access to the account. and the database whch the encrypted passwords are stored you cannnot access through the devtools
