Are there many sites that only support Authy's push authentication and nothing else?
No, not really, it's about migrating/restoring every single 2FA key would be extremely inconvenient
TOTP should just be a (typically base32) secret string; I don't know if Authy allows exporting that though (and if not, that only underscores the point of this article).
I just use a simple shell script with dmenu/xclip/oathtool:
#!/bin/zsh typeset -A opt=( Docker ABC GitHub DEF # ... ) k=$(print -l ${(ko)opt} | dmenu -i) [[ $k != "" ]] && oathtool --totp --base32 $opt[$k] | xclip -rmlastnl
