# Verification Methods

Age verification on websites is performed using **AgeGO’s verification methods**.

Each method is designed to determine either a user’s **exact age** or whether they fall within a **specific age range** (for example, 18+), depending on regulatory and business requirements.

An overview of all available methods can be found here:

**Age Verification Methods** → <https://www.agego.com/verification-methods>

Based on regulation and overall verification performance, AgeGO selects the verification method that best balances compliance and user experience.

## <mark style="color:$primary;">Method 1: Selfie</mark>

This method uses a **selfie-based age estimation** to assess a user’s age.

In some cases, an additional **government-issued photo ID** may be required to increase confidence or meet regulatory expectations.

## <mark style="color:$primary;">Method 2: Selfie + ID</mark>

This method combines a **live selfie** (with liveness detection) and a mandatory **government-issued photo ID** to fully verify a user’s age.

## <mark style="color:$primary;">Method 3: Credit Card</mark>

This method uses **credit card authorization** to confirm that a user is **18 years old or over**.

## <mark style="color:$primary;">Method 4: Digital ID</mark>

This method relies on a **third-party digital identity application**, such as **Yoti Digital ID**.

Requirements:

1. A smartphone or webcam.
2. A government-issued photo ID

Once a user has successfully verified their age through AgeGO, accessing age-restricted content becomes simpler on subsequent visits.

When a user visits a website that uses AgeGO:

* The user opens a site with age-restricted content.
* In the age-verification prompt, the user selects **“Already verified? Access here”**.
* The user chooses their preferred login method:
  * Email OTP (one-time code), or
  * Google Connect, or
  * Passkey Login (if previously set up).

{% tabs %}
{% tab title="Email OTP Login" %}

* The user enters their email address and continues.
* A one-time AgeGO code is sent to the provided email address.
* The user enters the received code into the verification prompt.
* Access to the content is granted.
  {% endtab %}

{% tab title="Google Connect" %}

* The user selects **Continue with Google**.
* The user authenticates using their device (e.g. Face ID, fingerprint, or device PIN).
* The Google account is linked to the user’s AgeGO profile.
* Access is granted.
  {% endtab %}

{% tab title="Passkey Login" %}

* If the user has previously set up a Passkey in their AgeGO account, they can choose **Passkey login**.
* The user authenticates using their device (e.g. Face ID, fingerprint, or device PIN).
* Access is granted instantly, without entering an email or code.
  {% endtab %}
  {% endtabs %}

This login flow allows returning users to confirm their previously verified status without repeating the full verification process.
