# Authentication Methods
> Residential Proxy Authentication Methods
We support residential proxy authentication via username and password or IP-based whitelisting.
You can manage **proxy users** and **whitelisted IPs** on the [**Residential → Residential → Authentication**](https://dashboard.decodo.com/residential-proxies/authentication) section on your dashboard.
* After you purchase a plan or subscription, a proxy username and password will be automatically generated in the Authentication section.
* The default number of whitelisted IP slots is **10**. Please [**contact**](https://direct.lc.chat/12092754/1) our customer support for more information.
### Dashboard Access
If you cannot log in to your dashboard, please request a password change by going to the [**Reset Password**](https://dashboard.decodo.com/password-reset) page.

## User:pass Authentication
### Managing Proxy Users
* You can manage your **proxy users** by clicking the **Users** tab in the Authentication section.
* You can **buy** additional users by clicking **Buy users** on the right.
Currently, you **cannot rename** proxy users. If needed, you can create a new one or recreate a proxy user by deleting it.
### Editing Proxy Users
* To **edit** a proxy user, click the **three dots** and then **Edit user**. A menu on the right will open.
* Alternatively, you can **add** or **edit** **proxy users**, generate **passwords**, and change their traffic limit directly in the [**Proxy setup**](https://dashboard.decodo.com/residential-proxies/proxy-setup) section.
### Password Generation
* To **change** your proxy user's **password**, click the **Generate password** button next to the password.
* To reveal or hide the password, click the **eye** icon.
* You can **copy** the username and password by clicking on them.
### Traffic Limit Management
1. To **add**, **edit**, or **remove** a **traffic limit** for a specific proxy user, click **Add traffic limit**.
2. Type in the traffic limit and click the checkmark button to add or edit a limit. Click **X** to cancel.
3. Click on **Edit** to change or the **Bin** icon to **remove** the traffic limit.
4. Click **Save**
### Proxy User Deletion
* To **delete** a proxy user, click **Remove user** and then **Confirm**.
### Adding an Extra Proxy User
1. To **create** a new proxy username and password, click **+ Add user**. A menu on the right will open.
* A vacancy is required for this option to appear. Check the **Total users** count.
2. Type in the username you want and click **+ Add**. A password will be automatically generated.
* The username must be 6 to 64 characters long, letters and numbers only, no spaces.
### 407 Error / Proxy Authentication Required
If you cannot authenticate with proxy user credentials, then try generating a new password.

## Whitelisted IP Authentication
### Managing Whitelisted IPs
1. You can manage your **whitelisted IPs** by clicking the **Whitelisted IPs** tab in the Authentication section.
* The list will be empty by default.
2. To **add** a new **IP address** to the whitelist, click **+ Add IP**. A menu on the right will open.
* To **buy** more than 10 Whitelisted IP slots, please contact our 24/7 customer support by clicking the chat widget on the bottom right or by using this [**link**](https://direct.lc.chat/12092754/1).
3. Enter your desired **IP address**, and click **+ Add** to whitelist it.
* You can only add IPs that are in **IPv4** format (xx.xx.xx.xx). The **IPv6** format is not supported.
* Ensure that the IP you are adding is yours, only accessible by you, and that you are not using a Proxy or VPN service at the time.
### Editing Whitelisted IPs
* To **edit** a whitelisted IP, click the **three dots** and then **Edit IP**. A menu on the right will open.
* Alternatively, you can **add** or **edit** **whitelisted IPs** directly in the [**Proxy setup**](https://dashboard.decodo.com/residential-proxies/proxy-setup) section.
### Naming Whitelisted IPs
* To **name** your whitelisted IP, click **Edit** and type in the name you want. Click **Save** to finalize.
* Leave the entry field blank to remove a name.
### Whitelisted IP Removal
* To **remove** a whitelisted IP, click **Remove Whitelisted IP** and then **Confirm**.
If you’re using services such as **Amazon Web Services**, we highly recommend using the traditional `username:password` authentication instead.
