This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

Currently having problems with GMail I lost my old phone (2fA)

Yea this is exactly why I don't use 2FA

If the password is like 64 characters randomly generated by Keepass, the 2FA doesn't matter.

Nah, any decent password manager or security application can manage multi-factor security credentials of any kind without failure due to phone loss.

Password authentication is beyond primitive by offering too many avenues of attack: the full secret is transmitted & shared. Passkeys, client certificates, OTP don't transmit the secret key. Passkeys & client certificates authentication never share a secret key, so the server can't expose it.

You can still accidentally leak your password via phishing or malware. 2FA is fine if you don't tie it to a phone number, simplest way: install any authenticator app for TOTP tokens. Scan the QR code on multiple devices like phone + tablet, or old phone, for redundancy. Or save the secret key.

Google and most critical services also give you a list of 10 single use emergency codes that you should print or save in Keepass - lost the phone? Nbd just use one of the codes and reset 2FA.

I also never thought my non shared password would be public but one day I suddenly got prompted on the authenticator if I wanted to login; still no idea how or why but at least no one could get in and immediately rotated out the password.

This is what I do as well. A few services force 2fa though and also have 0 good options (let me use my flipper as a u2f through not chrome, ungoogled-chromium works, but damn), and for those I'm forced to use text.

While I'm here, anyone have a good chrome based browser that is private and can use serial ports for flashing meshtastic devices and u2f? Need android mainly because I have ungoogled-chromium on linux, but will take recs for linux too if there's a better one.
