# Multifactor Authentication
In the UI settings, clients can set various security methods, both for logging in and transaction approval. If several people have access to the client record, we have an option to differentiate main users who will be able to approve transactions created by subordinate users.
In order to turn on this feature and use varios roles for account users, please contact our support.
In your profile, you can see the Tasks subsection. If you are "main" user, you will see transaction requests waiting for your approval there, as well as the data on previously processed requests.
The set of available security methods in terms of transactions is the same as for login: Email code, SMS code, 2-factor Authentication code, funding password. To turn this on you need to go to the Settings -> Security Methods.
When main user sets up some security protocol, the same will be required for all subordinate users.
During transaction initiation, when security methods are set, clients will see the following message:
If several Security methods are turned on, multiple codes can be requested.
If you are a subordinate user, you will see that the transaction is waiting for confirmation from main users.
This method is not represented in the API commands. In case you are a BaaS partner, please make sure to have separate users for API and UI.
In case of any questions, please contact our support team.
Only after all main users approve the transaction, it will be processed in the usual manner.
At the moment, we don't have any additional notifications apart from the one in UI, so please if you set this feature, make sure to inform your colleagues on the process to avoid possible transaction delays.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.delos.financial/baas-wiki/ui-overview/multifactor-authentication.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
