How Google Authenticator and Transaction Limits Help Protect Your KAST Account

Money can move fast. That is why account security should not start after something goes wrong.

At KAST, we give you tools to add stronger checks before money leaves your account. Google Authenticator helps protect sensitive actions. Transaction limits help control how much can move through transfers and card spending.

Together, they strengthen protection for your account and funds.

This guide explains why Google Authenticator and transaction limits matter, how they work in KAST, and how to set them in the app.

Why Google Authenticator and Limits Matter

Google Authenticator and transaction limits protect your KAST account in different ways.

Google Authenticator adds an extra security check. Transaction limits set boundaries for money movement.

That matters because unauthorized activity can start small. It may begin with a login attempt, a device issue, exposed card details, or a test payment. If the account has higher limits, more money may move before you notice.

With the right setup, we can add stronger verification around larger or unusual actions.

Security tool or control	What it helps with
SMS or email one-time passcode	Helps verify account access
Google Authenticator	Adds a second security check
Transaction limits	Set transfer and spending boundaries
Additional verification	May apply to larger or higher-risk actions
Card limits	Help control daily card spending

The goal is simple. Everyday activity should stay smooth, while larger or unusual activity may require stronger verification.

How Google Authenticator Adds Stronger Protection in KAST

We use one-time passcodes sent by SMS or email to help verify account access. This is your first layer of protection.

Google Authenticator adds another security check on top of that. This is your additional, second layer of protection in the KAST app.

Once enabled, we may use Google Authenticator for stronger verification when your account needs extra protection, such as during sensitive actions or higher-risk activity.

You can find it here:

Step	What to do
1	Open the KAST app
2	Tap your profile or name icon in the top-left corner
3	Open Security
4	Select Google Authenticator
5	Follow the setup steps in the app

Security settings may also include PIN settings, biometric login, device management, and discoverability controls.

Keep your Google Authenticator backup key somewhere safe. If you lose access to your device or authenticator app, account recovery may take longer.

How Transaction Limits Work in KAST

Transaction limits let you set boundaries for different types of account activity.

You can manage them in the KAST app:

Step	What to do
1	Open the KAST app
2	Tap your profile or name icon in the top-left corner
3	Open Limits
4	Choose the transaction type
5	Set the available daily or transaction limit

The Limits section shows the main categories in one place.

Limit category	What you can manage
KAST User Transfer	Daily limit and transaction limit
Bank Transfer	Daily limit and transaction limit
Onchain Transfer	Daily limit and transaction limit
Card Transaction	Daily card transaction limit

Each limit category protects a different type of movement.

KAST User Transfer limits help manage transfers to other KAST users. Bank Transfer limits help control bank payouts. Onchain Transfer limits matter because blockchain transfers are usually final after they are sent. Card Transaction limits help control daily card spending.

How Limits Add Stronger Protection

Limits are not only for budgeting. They also help protect your KAST account.

For some transfers, we may ask for a one-time passcode when the amount is below your limit. If the transaction goes above your limit, we may ask for additional verification, such as a face scan or Google Authenticator code.

For card spending, we may decline a transaction above your preset card limit.

If this happens	What may happen
Transfer is below your limit	We may ask for a one-time passcode
Transfer is above your limit	We may ask for enhanced security
Card transaction is above your limit	The transaction may be declined

This setup keeps everyday use simple while adding stronger checks around larger movements.

For example, you may use KAST for small transfers, daily card payments, or regular payouts. If your limits match your normal use, a much larger transaction will not move through in the same way.

How Limits Can Help Reduce Larger Losses

A transaction limit controls how much can move at once. A daily limit controls how much can move in total.

If someone tries to move more than your usual amount, we may ask for enhanced security, decline the transaction, or apply another control before a larger amount leaves your account.

This matters most for actions that can move quickly or may be hard to reverse. Onchain transfers are usually final once sent. Bank transfers may involve external rails and review steps. Card payments can happen quickly if card details were exposed.

Set limits around how you actually use KAST:

how much you usually send in one transfer
how much you usually spend with your card in one day
how often you use bank transfers
whether you use onchain transfers
which actions need tighter protection

You do not need the same limit for every category. Your card limit can differ from your bank transfer limit. Your onchain transfer limit can also be tighter than your KAST User Transfer limit.

Keep Your Verification Channels Secure

Your KAST account security also depends on the channels you use to receive verification codes.

Keep the email address linked to your KAST account secure. Also protect your mobile number if you receive codes by SMS or WhatsApp.

Lock your device, keep your SIM protected, and act quickly if your phone number suddenly loses service.

Never share one-time passcodes with anyone. KAST will not ask you to send verification codes through chat, email, or social media.

Set Up Your KAST Account Security

Google Authenticator and transaction limits work best when you set them before you need them.

Open Security and enable Google Authenticator. Then open Limits and review each transaction category.

No security setting can guarantee that fraud will never happen. However, Google Authenticator, transaction limits, and secure verification channels can help reduce the risk of larger losses if someone gets unauthorized access to your account.

If something looks suspicious, freeze your card where relevant, review your recent activity, and contact Concierge.
