//! Accounts exported from Winauth are in the following format:
//!
//! One account per line, with each account represented as a URL.
//!
//! ```ignore
//! otpauth://totp/Steam:<steamaccountname>?secret=<ABCDEFG1234_secret_dunno_what_for>&digits=5&issuer=Steam&deviceid=<URL_Escaped_device_name>&data=<url_encoded_data_json>
//! ```
//!
//! The `data` field is a URL encoded JSON object with the following fields:
//!
//! ```json
//! {"steamid":"<steam_id>","status":1,"shared_secret":"<shared_secret>","serial_number":"<serial_number>","revocation_code":"<revocation_code>","uri":"<uri>","server_time":"<server_time>","account_name":"<steam_login_name>","token_gid":"<token_gid>","identity_secret":"<identity_secret>","secret_1":"<secret_1>","steamguard_scheme":"2"}
//! ```
