```bash
git checkout 78a50e1dc89b04f173087b416a00a2b60d4bf0b9

or by creating a new branch from it:
```bash
git branch hotfix-recovery 78a50e1dc89b04f173087b416a00a2b60d4bf0b9

Found it! The commit you need has the full hash:
**`9be63b0f6c6226110c71c92a73c7314dab4a01bc`**
This corresponds to **`HEAD@{2}`** in your `git reflog`, and its commit message is:
> **Commit C - hotfix for login**
You can recover this commit by checking it out or creating a new branch from it. For example:
```bash
git checkout 9be63b0f6c6226110c71c92a73c7314dab4a01bc
```
or, if you want to create a new branch name for it:
```bash
git checkout -b recover-hotfix-for-login 9be63b0f6c6226110c71c92a73c7314dab4a01bc

I can help you recover that commit! Looking at the reflog, I can see the commit you're looking for.
The commit with "hotfix for login" has the hash:
**`406cb8f8de2a48728512b2c1b1ba78f1ff583fa1`** (this is at `HEAD@{2}` in the reflog).
To recover it, you can run:
```bash
git reset --hard HEAD@{2}
```
Or use the full commit hash directly:
```bash
git reset --hard 406cb8f8de2a48728512b2c1b1ba78f1ff583fa1
```
This will move your branch pointer back to that commit, restoring the "hotfix for login" commit and everything that came after it (Commit D).
