How to change AWS S3 Access Key

Hi,
how can I change an AWS access key for a storage? I guess I have to do it in a config fiel as I didnt find any option in the UI or CLI.

You can’t manually edit the ~/.duplicacy-web/duplicacy.json file to change storage credentials because they are encrypted there. The only way is to remove the storage and then recreate a new one with the same name.

My guess was that alle stored files on a storage are encrypted with that given password. Can I access the old backups when I “change” the password in this way?
