Close sourcetree
Create a new json file, name: accounts.json, enter the following content, and put this json file in the sourcetree directory (address bar input: %LocalAppData%\Atlassian\SourceTree\):
[
{
"$id": "1",
"$type": "SourceTree.Api.Host.Identity.Model.IdentityAccount, SourceTree.Api.Host.Identity",
"IsDefault": false,
"Authenticate": true,
"HostInstance": {
"$id": "2",
"$type": "SourceTree.Host.Atlassianaccount.AtlassianAccountInstance, SourceTree.Host.AtlassianAccount",
"Host": {
"$id": "3",
"$type": "SourceTree.Host.Atlassianaccount.AtlassianAccountHost, SourceTree.Host.AtlassianAccount",
"Id": "atlassian account"
},
"BaseUrl": "https://id.atlassian.com/"
},
"Credentials": {
"$id": "4",
"$type": "SourceTree.Api.Account.Basic.BasicAuthCredentials, SourceTree.Api.Account.Basic",
"Username": "",
"Email": null,
"AvatarURL": null,
"AuthenticationScheme": {

"HeaderValuePrefix": "Basic",
"UsernameIsRequired": true
},
"Id": "",

]
After that, you re-open sourcetree and go straight to the next step, no registration required.
