Two-Factor Authentication Integration

Automatically fetch 2FA verification codes from email, Slack, or Twilio SMS messages—no manual code entry required.

For TOTP codes from authenticator apps, see TOTP Integration.

Methods

Method	Source	Use Case
Email	Gmail inbox	Codes sent via email
Slack	Slack workspace	Codes sent via Slack
SMS	Twilio SMS	Codes sent via text

All methods follow the same pattern:

Fetch messages from the source (email inbox, Slack channel, or Twilio SMS)
Extract the 2FA code from matching messages
Store the code in the specified output_variable_name
Use {output_variable_name} in subsequent actions to input the code

Setup

Go to the Optexity dashboard → Integrations
Click the desired integration → Connect
Follow the prompts to grant access

Twilio SMS

Log in to your Twilio account and open the Twilio Console
Go to API Credentials and copy your Account SID and Auth Token
Add or select a Twilio phone number that will send or receive verification texts
Connect the Twilio integration in Optexity using the same credentials and phone number

Email 2FA

Fetch verification codes from email messages:

{
  "type": "action_node",
  "extraction_action": {
    "two_fa_action": {
      "action": {
        "type": "email_two_fa_action",
        "receiver_email_address": "user@example.com",
        "sender_email_address": "noreply@example.com",
        "integration_email_address": "automation-inbox@example.com"
      },
      "output_variable_name": "auth_code"
    }
  }
}

Properties

Property	Type	Required	Description
`receiver_email_address`	`str`	Yes	Recipient mailbox to search for 2FA emails
`sender_email_address`	`str`	Yes	Sender to filter (e.g., `noreply@site.com`)
`integration_email_address`	`str \| null`	No	Connected integration mailbox. Defaults to `receiver_email_address` if omitted

Use integration_email_address when the connected mailbox is different from the mailbox receiving the 2FA email (for example, alias/forwarding setups).

Slack 2FA

Fetch verification codes from Slack messages:

{
  "type": "action_node",
  "extraction_action": {
    "two_fa_action": {
      "action": {
        "type": "slack_two_fa_action",
        "slack_workspace_domain": "mycompany.slack.com",
        "channel_name": "security-codes",
        "sender_name": "Security Bot"
      },
      "output_variable_name": "auth_code"
    }
  }
}

Properties

Property	Type	Required	Description
`slack_workspace_domain`	`str`	Yes	Workspace domain (identifies integration)
`channel_name`	`str`	Yes	Channel containing the 2FA messages
`sender_name`	`str`	Yes	Name of the bot/user sending the codes

SMS 2FA

Fetch verification codes from Twilio SMS messages:

{
  "type": "action_node",
  "extraction_action": {
    "two_fa_action": {
      "action": {
        "type": "sms_two_fa_action",
        "from_number": "+18777804236",
        "to_number": "+19897878948"
      },
      "output_variable_name": "auth_code"
    }
  },
  "before_sleep_time": 3,
  "end_sleep_time": 0
}

Properties

Property	Type	Required	Description
`from_number`	`str`	Yes	Twilio phone number sending the SMS code
`to_number`	`str`	Yes	Destination phone number receiving the SMS

Common Properties

These apply to Email, Slack, and SMS 2FA:

Property	Type	Default	Description
`output_variable_name`	`str`	—	Variable name to store the extracted code
`instructions`	`str`	`None`	Optional custom instructions for code extraction
`max_wait_time`	`float`	`300.0`	Maximum wait time in seconds
`check_interval`	`float`	`10.0`	Polling interval in seconds

The action polls for the 2FA code every check_interval seconds until the code arrives or max_wait_time is reached.

Using the Code

Reference the extracted code in subsequent actions:

{
  "type": "action_node",
  "interaction_action": {
    "input_text": {
      "command": "get_by_label(\"Verification Code\")",
      "input_text": "{auth_code[0]}"
    }
  }
}
