What is a maFile
A maFile is a file that stores the data needed to use your account's Steam Guard.
It is needed for:
- generating login codes
- confirming trades and sales
- managing the authenticator
How NebulaAuth works with maFiles
When it starts, NebulaAuth automatically reads all maFiles from the maFiles folder in its data folder.
After that, they are displayed in the "Accounts" section inside the interface.
Tip
Unlike Steam Desktop Authenticator, SDA, NebulaAuth does not require the manifest.json file.
Where the files are located
NebulaAuth uses several folders:
maFiles— working accountsmaFiles_removed— deleted accountsmaFiles_backup— backup copies
With encryption on, the files in these folders are encrypted.
Security
Danger
Anyone with access to a maFile can use your Steam Guard.
Do not share these files with outsiders.
It is recommended to:
- store maFiles in a safe place
- make backup copies
- save the RCode, recovery code, separately
