+## Totp
+This module supports the migration of totp devices. The totp configuration block looks like this:
+```json
+{
+  "name": "Totp Device 1",
+  "secret": "secret",
+  "digits": 6,
+  "period": 30,
+  "algorithm": "HmacSHA1",
+  "encoding": "BASE32"
+}
+```
+name should be the name of the totp device, while secret is the secret, that could be encoded in "BASE32" or as the utf8 bytes. 
+For the utf8 bytes just set the encoding attribute to null.
+Possible Algorithms are: HmacSHA1, HmacSHA256, HmacSHA512
