Google is disabling password access altogether
I got the following email yesterday:
From: The G Suite Team
Beginning June 15, 2020, non-Google apps that use only a password to access
Google accounts will no longer be supported.
Starting February 15, 2021, G Suite accounts will only allow access to apps
using OAuth. Password-based access will no longer be supported.
Dear Administrator,
We're constantly working to improve the security of your organization's
Google accounts. As part of this effort, and in consideration of the
current threat landscape, we'll be turning off access to less secure apps
(LSA) — non-Google apps that can access your Google account with only a
username and password, without requiring any additional verification steps.
Access through only a username and password makes your account more
vulnerable to hijacking attempts. Moving forward, only apps that support a
more modern and secure access method called OAuth will be able to access
your G Suite account.
Access to LSAs will be turned off in two stages:
June 15, 2020 - Users who try to connect to an LSA for the first time will
no longer be able to do so. This includes third-party apps that allow
password-only access to Google calendars, contacts, and email via protocols
such as CalDAV, CardDAV and IMAP. Users who have connected to LSAs prior to
this date will be able to continue using them until usage of all LSAs is
turned off.
February 15, 2021 - Access to LSAs will be turned off for all G Suite
accounts.
What do I need to do?
To continue using a specific app with your G Suite accounts, users in your
organization must switch to a more secure type of access called OAuth. This
connection method allows apps to access accounts with a digital key instead
of requiring a user to reveal their username and password. We recommend
that you share the user instructions (included below) with individuals in
your organization to help them make the necessary changes. Alternatively,
if your organization is using custom tools, you can ask the developer of
the tool to update it to use OAuth. Developer instructions are also
included below.
MDM configuration
If your organization uses a mobile device management (MDM) provider to
configure CalDAV, CardDAV, and Exchange ActiveSync (Google Sync) profiles,
these services will be phased out according to the timeline below:
June 15, 2020 - MDM push of IMAP, CalDAV, CardDAV, and Exchange ActiveSync
(Google Sync) will no longer work for new users.
February 15, 2021 - MDM push of IMAP, CalDAV, CardDAV, and Exchange
ActiveSync (Google Sync) will no longer work for existing users. Admins
will need to push a Google Account using their MDM provider, which will
re-add their Google accounts to iOS devices using OAuth.
Other less secure apps
For any other LSA, ask the developer of the app you are using to start
supporting OAuth.
If you use other apps on iOS or MacOS that access your G Suite account
information through only a password, most access issues can be resolved by
removing then re-adding your account. When you add it back, make sure to
select Google as the account type to automatically use OAuth.
Scanners and other devices
No change is required for scanners or other devices using simple mail
transfer protocol (SMTP) or LSAs to send emails. If you replace your
device, look for one that sends email using OAuth.
User instructions
If you are using an app that accesses your Google account with only a
username and password, take one of the following actions to switch to a
more secure method and continue to access your email, calendar, or
contacts. If you do not take one of the following actions, when LSA access
is discontinued after February 15, 2021, you will begin receiving an error
message that your username-password combination is incorrect.
Email
If you are using stand-alone Outlook 2016 or earlier, move to Office 365 (a
web-based version of Outlook) or Outlook 2019, both of which support OAuth
access. Alternatively you can use G Suite Sync for Microsoft Outlook.
If you are using Thunderbird or another email client, re-add your Google
Account and configure it to use IMAP with OAuth.
If you are using the mail app on iOS or MacOS, or Outlook for Mac, and use
only a password to login, you'll need to remove and re-add your account.
When you add it back, select “sign in with Google” to automatically use
OAuth.

Calendar
If you use CalDAV to give an app or device access to your calendar, switch
to a method that supports OAuth. We recommend the Google Calendar app
[Web/iOS/Android] as the most secure app to use with your G Suite account.
If your G Suite account is linked to the calendar app in iOS or MacOS and
