+For that `autorestic` allows passing the env variables to backend password as `ENV` variables, or through an env file.
+You can also pass whatever `env` variable to restic by prefixing it with `AUTORESTIC_[BACKEND NAME]_`.
 
-The syntax for the `ENV` variables is as follows: `AUTORESTIC_[BACKEND NAME]_KEY`.
+> ℹ️ Env variables and file overwrite the config file in the following order:
+>
+> Env Variables > Env File (`.autorestic.env`) > Config file (`.autorestic.yaml`)
+
+## Env file
+
+Alternatively `autorestic` can load an env file, located next to `.autorestic.yml` called `.autorestic.env`.
+
+```
+AUTORESTIC_FOO_RESTIC_PASSWORD=secret123
+```
+
+### Example with repository password
+
+The syntax for the `ENV` variables is as follows: `AUTORESTIC_[BACKEND NAME]_RESTIC_PASSWORD`.
 
 ```yaml | autorestic.yaml
 backend:
   foo:
     type: ...
     path: ...
-    key: secret123 # => AUTORESTIC_FOO_KEY=secret123
+    key: secret123 # => AUTORESTIC_FOO_RESTIC_PASSWORD=secret123
 ```
 
-## Example
-
 This means we could remove `key: secret123` from `.autorestic.yaml` and execute as follows:
 
 ```bash
-AUTORESTIC_FOO_KEY=secret123 autorestic backup ...
+AUTORESTIC_FOO_RESTIC_PASSWORD=secret123 autorestic backup ...
 ```
 
-## Env file
+### Example with Backblaze B2
+
+```yaml | autorestic.yaml
+backends:
+  bb:
+    type: b2
+    path: myBucket
+    key: myPassword
+    env:
+      B2_ACCOUNT_ID: 123
+      B2_ACCOUNT_KEY: 456
+```
 
-Alternatively `autorestic` can load an env file, located next to `autorestic.yml` called `.autorestic.env`.
+You could create an `.autorestic.env` or pass the following `ENV` variables to autorestic:
 
-```| .autorestic.env
-AUTORESTIC_FOO_KEY=secret123
+```
+AUTORESTIC_BB_RESTIC_PASSWORD=myPassword
+AUTORESTIC_BB_B2_ACCOUNT_ID=123
+AUTORESTIC_BB_B2_ACCOUNT_KEY=456
 ```
 
-after that you can simply use `autorestic` as your are used to.
