When it comes to email clients, Mozilla Thunderbird stands out as a popular choice due to its flexibility and customizability. However, with the increasing emphasis on security, it's crucial to ensure that your email access is secure, especially when using third-party clients. That's where OAuth 2.0 comes into play, providing a secure way to authorize Thunderbird to access your Gmail account. In this article, we'll guide you through the 12 steps to configure Thunderbird for Gmail OAuth 2.0.

Step 1: Update Thunderbird

Before starting the configuration process, ensure that you have the latest version of Thunderbird installed. Updates often include security patches and bug fixes, essential for smooth OAuth 2.0 integration.

Step 2: Enable IMAP in Gmail

Log into your Gmail account and navigate to Settings. Under the "Forwarding and POP/IMAP" tab, ensure that IMAP is enabled. This allows Thunderbird to access your Gmail messages.

Step 3: Open Thunderbird Account Settings

Launch Thunderbird and go to "Tools" > "Account Settings". This will open a new window where you can manage your email accounts.

Step 4: Add a New Account

Click on the "Account Actions" button and select "Add Mail Account". A wizard will guide you through the process of setting up a new account.

Step 5: Enter Your Gmail Credentials

In the wizard, enter your name, Gmail address, and password. Thunderbird will attempt to automatically configure your account.

Step 6: Manual Configuration (If Needed)

If automatic configuration fails, you may need to manually set up your account. Select "Manual config" and enter the following details:

• Incoming: IMAP, imap.gmail.com, Port 993, SSL/TLS
• Outgoing: SMTP, smtp.gmail.com, Port 587, STARTTLS

Step 7: Select OAuth 2.0 as Authentication Method

In the account settings, find the authentication method for both incoming and outgoing servers and select OAuth 2.0.
