Similarly, let's suppose you enable **Voice calls** for a group. After you enable it, you find that even users who aren't group members can sign-in with a voice call. In this case, it's likely those users are enabled for **Mobile phone** in the legacy SSPR policy or **Call to phone** in the legacy MFA policy.

8080
The Authentication methods policy provides a migration path toward unified administration of all authentication methods. All desired methods can be enabled in the Authentication methods policy. Methods in the legacy MFA and SSPR policies can be disabled. Migration has three settings to let you move at your own pace, and avoid problems with sign-in or SSPR during the transition. After migration is complete, you'll centralize control over authentication methods for both sign-in and SSPR in a single place, and the legacy MFA and SSPR policies will be disabled.

# Web browser cookies used in Azure Active Directory authentication
21+
22+
During authentication against Azure Active Directory (Azure AD) through a web browser, multiple cookies are involved in the process. Some of the cookies are common on all requests. Other cookies are used for specific authentication flows or specific client-side conditions.
23+
24+
Persistent session tokens are stored as persistent cookies on the web browser's cookie jar. Non-persistent session tokens are stored as session cookies on the web browser, and are destroyed when the browser session is closed.
25+
26+
| Cookie Name | Type | Comments |
27+
|--|--|--|
28+
| ESTSAUTH | Common | Contains user's session information to facilitate SSO. Transient. |
29+
| ESTSAUTHPERSISTENT | Common | Contains user's session information to facilitate SSO. Persistent. |
30+
| ESTSAUTHLIGHT | Common | Contains Session GUID Information. Lite session state cookie used exclusively by client-side JavaScript in order to facilitate OIDC sign-out. Security feature. |
31+
| SignInStateCookie | Common | Contains list of services accessed to facilitate sign-out. No user information. Security feature. |
32+
| CCState | Common | Contains session information state to be used between Azure AD and the [Azure AD Backup Authentication Service](../conditional-access/resilience-defaults.md). |
33+
| buid | Common | Tracks browser related information. Used for service telemetry and protection mechanisms. |
34+
| fpc | Common | Tracks browser related information. Used for tracking requests and throttling. |

36+
| ch | Common | ProofOfPossessionCookie. Stores the Proof of Possession cookie hash to the user agent. |
37+
| ESTSSC | Common | Legacy cookie containing session count information no longer used. |
38+
| ESTSSSOTILES | Common | Tracks session sign-out. When present and not expired, with value "ESTSSSOTILES=1", it will interrupt SSO, for specific SSO authentication model, and will present tiles for user account selection. |
39+
| AADSSOTILES | Common | Tracks session sign-out. Similar to ESTSSSOTILES but for other specific SSO authentication model. |
40+
| ESTSUSERLIST | Common | Tracks Browser SSO user's list. |
41+
| SSOCOOKIEPULLED | Common | Prevents looping on specific scenarios. No user information. |
42+
| cltm | Common | For telemetry purposes. Tracks AppVersion, ClientFlight and Network type. |
43+
| brcap | Common | Client-side cookie (set by JavaScript) to validate client/web browser's touch capabilities. |

48+
| stsservicecookie | Common | Azure AD Gateway cookie also used for tracking purposes. |
49+
| x-ms-refreshtokencredential | Specific | Available when [Primary Refresh Token (PRT)](../devices/concept-primary-refresh-token.md) is in use. |
50+
| estsStateTransient | Specific | Applicable to new session information model only. Transient. |
51+
| estsStatePersistent | Specific | Same as estsStateTransient, but persistent. |
52+
| ESTSNCLOGIN | Specific | National Cloud Login related Cookie. |
53+
| UsGovTraffic | Specific | US Gov Cloud Traffic Cookie. |
54+
| ESTSWCTXFLOWTOKEN | Specific | Saves flowToken information when redirecting to ADFS. |
55+
| CcsNtv | Specific | To control when Azure AD Gateway will send requests to [Azure AD Backup Authentication Service](../conditional-access/resilience-defaults.md). Native flows. |
56+
| CcsWeb | Specific | To control when Azure AD Gateway will send requests to [Azure AD Backup Authentication Service](../conditional-access/resilience-defaults.md). Web flows. |
57+
| Ccs* | Specific | Cookies with prefix Ccs*, have the same purpose as the ones without prefix, but only apply when [Azure AD Backup Authentication Service](../conditional-access/resilience-defaults.md) is in use. |
58+
| threxp | Specific | Used for throttling control. |
59+
| rrc | Specific | Cookie used to identify a recent B2B invitation redemption. |
60+
| debug | Specific | Cookie used to track if user's browser session is enabled for DebugMode. |
61+
| MSFPC | Specific | This cookie is not specific to any ESTS flow, but is sometimes present. It applies to all Microsoft Sites (when accepted by users). Identifies unique web browsers visiting Microsoft sites. It's used for advertising, site analytics, and other operational purposes. |
62+
63+
> [!NOTE]
64+
> Cookies identified as client-side cookies are set locally on the client device by JavaScript, hence, will be marked with HttpOnly=false.
65+
>
66+
> Cookie definitions and respective names are subject to change at any moment in time according to Azure AD service requirements.
