Is your feature request related to a problem? Please describe.
I've had several occasions when I wanted to retype the TOTP secret (not the code, but the secret key) from the edit dialog. For instance when transferring to a device which doesn't have a camera for the QR code. In all of those occasions I had issues recognizing 0s from Os.

Describe the solution you'd like
In the edit dialog for the entries, use font with slashed zero 0.

Describe alternatives you've considered
Copying and sending the code via some app to the device, which only works with network access between the devices and is potentially slower for one-time use.

Additional context
