Question

Deleting SSH key with lost passphrase and adding new?

I’m new to this so please be kind. Despite noting down my SSH key passphrase, it isn’t working. I just want to enable the droplet console but can’t log in to my Droplet via SSH to do it.

Is it possible to delete or replace my local SSH key pair and the key on my droplet, and regenerate from scratch?

I set up my website fine, but not being able to access the file structure means I’m now stuck. I’ve read as much as I can to fix it but I’m clearly completely out of my depth… Unfortunately my developer has shut up shop, hence trying to navigate it myself.

Hi @lewisshark,

Yes, that’s pretty straightforward. First, make sure to create a new SSH key on your Laptop/Computer. Use the following procedure to generate an SSH key pair on UNIX and UNIX-like systems:

Run the ssh-keygen command.

You can use the -t option to specify the type of key to create.

For example, to create an RSA key, run:

  1. ssh-keygen -t rsa

You can use the -b option to specify the length (bit size) of the key, as shown in the following example:

  1. ssh-keygen -b 2048 -t rsa

Once you have an SSH key, you just need to enter your Droplet and replace them. Apart from the article about SSH keys being mentioned, you can use the following one as well:

Hi there,

I recently answered a similar question here.

You can change the passphrase of your SSH key by following the steps here:

To change the passphrase for your SSH key, you could use the following command:

ssh-keygen -p -f ~/.ssh/id_rsa

You will be asked to enter the old passphrase first followed by your new passphrase. The output would look something like this:

Enter old passphrase: ****
Enter new passphrase (empty for no passphrase): ****
Enter same passphrase again:                    ****
Your identification has been saved with the new passphrase.

In case that you prefer to generate a new SSH key and add it to your Droplet, you can follow the steps here:

Hope that this helps!
