celluloid VS OTPClient

Also their readme ( https://github.com/celluloid-player/celluloid ) suggests there is an RPM package via dnf. Why use flatpak?

Personally I use the mpv-amd-full-git package with the Celluloid fronted. Haruna works fine but it loses some functionality compared to Celluloid, like adding an external audio to a movie. Haruna is far superior in terms of front-end design.

Celluloid

gnome-mpv was abandoned and forked into Celluloid: https://github.com/celluloid-player/celluloid

For those who don't know, Celluloid (which ships with mint) is just a better (imo) frontend for MPV

Both VLC and MPV frontends like Celluloid give you keyboard control over playback speed.

There are GUIs based on mpv that provide a user-friendly interface and just use mpv for playback, see Celluloid [0].

My problem is that Aegis (open source) does not have a Linux app so I have to use an alternative. I found OTPClient, and it seems to fit the bill for a privacy concerns, but I can't figure out how to add it in PayPal as a second device to authenticate with.

If so, check out OTPClient.

Otpclient keep password manager and totp separate .

You can export your secret keys from Aegis, then import them into OTPClient if you want to use it on Desktop. That's the benefit of Aegis being FOSS. Your are not locked in to only using their products.

You didn't share your OS, but on Linux you could use Authenticator or OTPClient. If you want something cross-platform that will sync to multiple devices like Authy, you could give TokenVault in Standard Notes a try.

Expanding on the recommendations here, if you have some old laptop laying around (or can buy one on the cheap off e.g. Craigslist or something), you could install some Linux distro on it, install an OTP generator app (e.g. OTPClient, and then disconnect it from the network entirely. This would probably be considerably more secure than even using a phone, since the only way for someone to steal your TOTP keys would be to have physical access to the machine (and even that can be mitigated, seeing as how any reasonably-modern Linux distro will support full-disk encryption).

OTPClient is what I use. The source code is on github here
