Tap, Tap (version 1610): double tap on back of device

This app has double tap with sensitivity adjustment, works perfectly for me with no noticeable battery drain. https://github.com/KieronQuinn/TapTap

Just a quick shout-out of an app I discovered, it's a backport of quick tap for older android versions, but also has sensitivity adjustments and works great for me. Always triggers when I double tap (unlike the originl) and I've never had it accidentally trigger. https://github.com/KieronQuinn/TapTap

That said, some apps do use Material Design 3: Sync, Simple File Manager, Auxio Tap, Tap

Github

Tap Tap provides customizable tap routines

Tap, Tap (version 1600): double tap on back of device

there also is an app named "tap tap" available on GibHub with direct integration as Tasker Plugin.

Have a look at Tap, Tap.

I don't know why people keep saying this. This app has been around for a while now and works flawlessly, as close to automatic as you can get: https://github.com/alexzorin/authy

Authy totp tokens can be exported from Authy using https://github.com/alexzorin/authy

Just use the totp token as the first entry in the password file, and "pass otp " will generate an otp. Very convenient.

Easy to export

There's project that can export Authy tokens for you to import in Aegis. And every time you add a new token, just scan the QR code with both Authy and Aegis, they are back up for each other (so in case one of them stops working you can use the other one). Authy is also great if you have devices other than Android (Windows, iPhone/iPad, etc.)

Refer: code to extract 2FA seeds from Authy or use this App on github to extract seeds.
