Most common email providers no longer allow applications to send an email with only a username and password for security reasons. This means that even though you may enter your password correctly in coreFORCE, you will still get an "authentication failed" error. You need to create an app password which will be used only by coreFORCE.
It was previously possible to turn on a setting called "Allow less secure apps" in your Google account to send email with a username and password, but Google has removed that setting for all accounts.
SIGN IN WITH APP PASSWORDS
An App Password is a 16-character passcode that gives a less secure app or device permission to access your Google Account. App Passwords can only be used with accounts that have 2-Step Verification turned on.
Create & use App Passwords
You must turn on 2-Step-Verification in order to use an App Password to send email with Google.
- Go to your Google Account.
- Select Security.
- Under "Signing in to Google," select App Passwords. You may need to sign in. If you don’t have this option, it might be because:
- 2-Step Verification is not set up for your account.
- 2-Step Verification is only set up for security keys.
- Your account is through work, school, or other organization.
- You turned on Advanced Protection.
- At the bottom, choose Select app and choose the app you using Select device and choose the device you’re using ("Other (custom)") Generate.
- Follow the instructions to enter the App Password. The App Password is the 16-character code in the yellow bar on your device.
- Tap Done.
Tip: Most of the time, you’ll only have to enter an App password once per app or device, so don’t worry about memorizing it.
App-specific passwords allow you to sign in to your account securely when you use third-party apps with your Apple ID.
App-specific passwords are passwords for your Apple ID that let you sign in to your account and securely access the information you store in iCloud from a third-party app. For example, use app-specific passwords with mail, contacts, and calendar services not provided by Apple. App-specific passwords maintain a high level of security and help ensure your Apple ID password won’t be collected or stored by any third-party apps you use.
If you are signed in to iCloud for Windows, you don't need an app-specific password when using your Apple ID with third-party Microsoft apps.
To generate and use app-specific passwords, your Apple ID must be protected with two-factor authentication.
You also need an app-specific password for your devices that use Mac OS X Lion 10.7.5 and earlier or iOS 5 and earlier. If you don’t have devices that can be updated to iOS 9 or later or OS X El Capitan or later, you can set up two-step verification and generate app-specific passwords.
How to generate an app-specific password
- Sign in to your Apple ID account page.
- In the Security section, click Generate Password below App-Specific Passwords.
- Follow the steps on your screen.
After you generate your app-specific password, enter or paste it into the password field of the app as you would normally.
How to manage app-specific passwords
At any given time, you can have up to 25 active app-specific passwords. If you need to, you can revoke passwords individually or all at once.
- Sign in to your Apple ID account page.
- In the Security section, click Edit.
- In the App-Specific Passwords section, click View History.
- Click next to a password you want to delete or Revoke All.
After you revoke a password, the app using that password will be signed out of your account until you generate a new password and sign in again.
Any time you change or reset your primary Apple ID password, all of your app-specific passwords are revoked automatically to protect the security of your account. You'll need to generate new app-specific passwords for any apps that you want to continue using.
Important note: Microsoft has announced that basic authentication (logging in with a username and password) will be disabled for ALL accounts in early 2023. There are no exceptions for App passwords. Creating an app password in Microsoft 365 will not help with authentication issues. We plan to add support for OAuth (which Microsoft calls "Modern authentication") but there is no timeline for this yet. At this time, clients are encouraged to use a different email provider with coreFORCE/coreFIRE.
How to create a new app password
To create a new app password for an app or device, take the following steps. You can repeat these steps to create an app password for as many apps or devices as you need.
Go to the Security basics page and sign in to your Microsoft account.
Select More security options.
Under App passwords, select Create a new app password. A new app password is generated and appears on your screen.
Enter this app password where you would enter your normal Microsoft account password in the application.
