My hard drive crashed and was completely wiped clean. My new computer with Windows 11 was downloaded using my backup external hard drive. My e-mail is through AT&T but my Thunderbird account has all my messages and addresses. I have attempted to sign into the new Thunderbird download but it won't recognize my password. How can I find the password or a way to change the password in order to access my Thunderbird account?

I believe ATT requires either OAUTH authentication or a ATT secure key. I suggest you check at ATT for this. A web search for att secure mail key should get you to the right place.
