Visual Studio Code で Bitbucket を使う（2022年3月1日以降）

久しぶりに Bitbucket のリポジトリをクローンしようとしたら以下のエラー。

fatal: Invalid credentials
remote: Bitbucket Cloud recently stopped supporting account passwords for Git authentication.
remote: See our community post for more details: https://atlassian.community/t5/x/x/ba-p/1948231
remote: App passwords are recommended for most use cases and can be created in your Personal settings:
remote: https://bitbucket.org/account/settings/app-passwords/
fatal: Authentication failed for 'https://bitbucket.org/foo/bar.git/'

https://atlassian.community/t5/x/x/ba-p/1948231 を確認してみたら、

Bitbucket Cloud users will no longer be able to use their account passwords when using Basic authentication for Git over HTTPS and the Bitbucket Cloud REST API.

ということらしいです。
