How do I change my username/email on Cryptomator?
What do you mean by “on Cryptomator”? Cryptomator (the application itself) doesn’t have any user accounts so there’s nothing to change. If you mean this community/forum, you should be able to change your username in the preferences (at the top right under the “user” icon). If you’re referring to an email address associated with a license, send the support team an email.
You are absolutely correct. I meant the forum. I have now sorted it out. Thanks.
Just sent you a direct message.
I am going to be kicked out of this forum soon for stupidity. How do I get to direct messages.
Also at the top right but under the “mail” icon.
