I was forced to change my email password and desperately searched for where to put the new smtp\_password in the admin panel.
I finally understood (here) that it was necessary to go through a modification of a file (yaml?). I have SSH access, but I am not at all comfortable with it. Could someone give me a link or complete explanations so that I can manage it: the command to edit the file to modify, where to put the smtp\_password (should it be encoded?), save the file? restart Discord?
Thanks in advance.

Hi there, all you need to do is SSH in, and just do this:
```plaintext
nano containers/app.yml
```
That will open up the text editor to change the SMTP details.
Then, you can run:
```plaintext
cd /var/discourse
./launcher destroy app
./launcher start app
```
for the changes to take effect.
A simpler way would be to run `./discourse-setup` again, and fill out the details again.

Thank you very much for this fast answer.
If I run `./discourse-setup All my settings will be destroyed ?`

No, I don’t believe it does. I would suggest the first option, if you have more things to edit.

`.\discourse-setup` will likely not work, use `.\launcher rebuild app` after CTRL+x in `nano containers/app.yml`

Thank you all for the quick replies. I’m summarizing [and updating with subsequent info] for beginners like me:
- Back up the database
- Connect via SSH
- Edit the file containing the password
`sudo nano /var/discourse/containers/app.yml`
- Find the line containing the password
`DISCOURSE_SMTP_PASSWORD: “your_smtp_password”`
- Enter the new password in plain text (deleting the old one)
- Save the new file: Ctrl+X, then confirm O (yes) or Y (yes), then Enter
- Rebuild (this may take time)
`cd /var/discourse`
`./launcher rebuild app`
- If only SMTP details were modified, you can limit yourself to
```plaintext
cd /var/discourse
./launcher destroy app
./launcher start app
```
for the changes to take effect.

i would recommend backing up the database before (and after) rebuild, but you probably did that before logging in via SSH
i like that you’ve included instructions for how to use the `nano` text editor

Do I have to rebuild? Rebuilding is too slow 😩

Running discourse-setup is the easiest way for a novice. It will do a rebuild automatically (unless you control-c before it does).
Editing with nano (or vim) and destroy/start is the fastest way, though if you have upgraded with docker\_manager from the ux it’ll undo those changes and you might need to rebuild anyway.
