Upgrading from MSAL Angular v3 to v4

MSAL Angular v4 includes security updates from MSAL Browser and adds Angular 19 support to the existing Angular 15-18 support.

Please see the MSAL Browser v3 migration guide for browser support and other key changes.

Changes in @azure/msal-angular@4

Using local storage

Due to changes in MSAL Browser related to local storage encryption, please ensure you are checking that initialization has completed and that interaction status is None before calling any account APIs.

this.msalBroadcastService.inProgress$
    .pipe(
        filter(
            (status: InteractionStatus) => status === InteractionStatus.None
        ),
        takeUntil(this._destroying$)
    )
    .subscribe(() => {
        this.loginDisplay = this.authService.instance.getAllAccounts().length > 0;
    });
