Google in June 2022 increased the security level needed to access its Gmail service, and as a result some Eudora email users can no longer access their accounts that run through Gmail, such as the Telus and Shaw ISPs in Canada. The error message may read similar to this one:
ERR [AUTH] Username and password not accepted.
The error message tells us that Eudora has a problem with authenticating who you are to Gmail, and that the username and password are unacceptable to Google. Google had been warning that this would be occurring, but it is not always easy to understand the implications to changes to the Internet's infrastructure.
To prove to Google who you are, you need to enter into Eudora a password generated by Google just once. Google calls the password it generates an “app password.” It is 16 letters long, and lets Google know that you are giving Eudora permission to access your Gmail account. There are two stages to fixing the problem: first, increase your security level with Google by turning on two-step authentication, and then decrease it.
Stage 1: Add Two-Step Authentication to Your Google Account
If you do not already have two-step authentication turned on, or if you don't know whether you have it turned on, then follow these steps:
1. Open your Web browser, and go to https://myaccount.google.com/
2. Enter your Google password, should you be asked for it.
3. On the left side, click Security.
4. Under Signing in to Google, look for 2-step Verification:
- If it is on, then there is a blue check mark
- If it is off, then click 2-step Verification. Google will ask for your password, and then you turn on 2-step verification.
TIP Two-step authentication means that Google will confirm who you are by asking you in a second way. Most commonly, it will send you a notification on another one of your devices, such as your Android phone. You can choose which device to send the notification to, and whether the notification should be sent only once when accessing your account on a new device, like a friend's computer. I recommend the once-only option.
With the security level of your Google account increased, Google now allows you to decrease it for Eudora.
Stage 2: Obtain a Temporary Google-generated Password
With two-step authentication set up, the second part to getting Eudora working with GMail again is to obtain a one-time password that Google generates. This lets Google know that it is okay for your email software to access your Gmail account. Follow these steps:
1. Staying in Google Account's Security page, click App Passwords
2. You will need to enter your Google password to prove to Google you are who you are.
3. Click Next.
4. In the App passwords page:
a. Under Select App, choose Mail
b. Under Select Device, choose a device, such as Windows Computer
c. Click Generate
5. In the Generated app Password dialog box, an app password appears. Copy it.
Notice that Google immediately sends you a warning email /and/or message to your phone about the security change made to your account. Click Yes, It Was Me. This is two-factor authentication at work.
6. Start Eudora, and when it asks for a password, enter the one Google generated for you.
