Methods

acquireTokenSilent(SilentRequest)	Silently acquire an access token for a given set of scopes. Returns currently processing promise if parallel requests are made.
loginPopup(PopupRequest)	Use when initiating the login process via opening a popup window in the user's browser
loginRedirect(RedirectRequest)	Use when initiating the login process by redirecting the user's browser to the authorization endpoint. This function redirects the page, so any code that follows this function will not execute. IMPORTANT: It is NOT recommended to have code that is dependent on the resolution of the Promise. This function will navigate away from the current browser window. It currently returns a Promise in order to reflect the asynchronous nature of the code running in this function.

Inherited Methods

acquireTokenByCode(AuthorizationCodeRequest)	This function redeems an authorization code (passed as code) from the eSTS token endpoint. This authorization code should be acquired server-side using a confidential client to acquire a spa_code. This API is not indended for normal authorization code acquisition and redemption. Redemption of this authorization code will not require PKCE, as it was acquired by a confidential client.
acquireTokenPopup(PopupRequest)	Use when you want to obtain an access_token for your API via opening a popup window in the user's browser
acquireTokenRedirect(RedirectRequest)	Use when you want to obtain an access_token for your API by redirecting the user's browser window to the authorization endpoint. This function redirects the page, so any code that follows this function will not execute. IMPORTANT: It is NOT recommended to have code that is dependent on the resolution of the Promise. This function will navigate away from the current browser window. It currently returns a Promise in order to reflect the asynchronous nature of the code running in this function.
addEventCallback(EventCallbackFunction)	Adds event callbacks to array
addPerformanceCallback(PerformanceCallbackFunction)	Registers a callback to receive performance events.
disableAccountStorageEvents()	Removes event listener that emits an event when a user account is added or removed from localstorage in a different browser tab or window
enableAccountStorageEvents()	Adds event listener that emits an event when a user account is added or removed from localstorage in a different browser tab or window
getAccountByHomeId(string)	Returns the signed in account matching homeAccountId. (the account object is created at the time of successful login) or null when no matching account is found
getAccountByLocalId(string)	Returns the signed in account matching localAccountId. (the account object is created at the time of successful login) or null when no matching account is found
getAccountByUsername(string)	Returns the signed in account matching username. (the account object is created at the time of successful login) or null when no matching account is found. This API is provided for convenience but getAccountById should be used for best reliability
getActiveAccount()	Gets the currently active account
getAllAccounts()	Returns all accounts that MSAL currently has data for. (the account object is created at the time of successful login) or empty array when no accounts are found
getConfiguration()	Returns the configuration object
getLogger()	Returns the logger instance
getTokenCache()	Gets the token cache for the application.
handleRedirectPromise(string)	Event handler function which allows users to fire events after the PublicClientApplication object has loaded during redirect flows. This should be invoked on all page loads involved in redirect auth flows.
initialize()	Initializer function to perform async startup tasks such as connecting to WAM extension
initializeWrapperLibrary(WrapperSKU, string)	Called by wrapper libraries (Angular & React) to set SKU and Version passed down to telemetry, logger, etc.
logout(EndSessionRequest)	Deprecated logout function. Use logoutRedirect or logoutPopup instead
logoutPopup(EndSessionPopupRequest)	Clears local cache for the current user then opens a popup window prompting the user to sign-out of the server
logoutRedirect(EndSessionRequest)	Use to log out the current user, and redirect the user to the postLogoutRedirectUri. Default behaviour is to redirect the user to window.location.href.
removeEventCallback(string)	Removes callback with provided id from callback array
removePerformanceCallback(string)	Removes a callback registered with addPerformanceCallback.
setActiveAccount(AccountInfo | null)	Sets the account to use as the active account. If no account is passed to the acquireToken APIs, then MSAL will use this active account.
setLogger(Logger)	Replaces the default logger set in configurations with new Logger with new configurations
setNavigationClient(INavigationClient)	Sets navigation client
ssoSilent(SsoSilentRequest)	This function uses a hidden iframe to fetch an authorization code from the eSTS. There are cases where this may not work: Any browser using a form of Intelligent Tracking Prevention If there is not an established session with the service In these cases, the request must be done inside a popup or full frame redirect. For the cases where interaction is required, you cannot send a request with prompt=none. If your refresh token has expired, you can use this function to fetch a new set of tokens silently as long as you session on the server still exists.
