Super mais 3 petites choses à dire

L’app est vraiment excellente, la plus propre et fonctionnelle que j’ai testé (et j’en ai testé pas mal !).
3 petits changements seraient toutefois les bienvenus :
- sur l’écran d’accueil, l’app s’appelle « ProtonAuthentic… ». Un nom plus court qui ne serait pas tronqué serait évidemment mieux.
- il est impossible de personnaliser les images illustrants les comptes.
Exemple : un compte nommé « Amazon » aura bien le logo de l’entreprise mais un compte nommé « Amazon Julien » et un 2ème « Amazon Aurélie » auront droit à l’initiale du titre seulement.
- pas mal de sites ne sont pas reconnus et n’ont donc pas droit à leur logo (Adobe, Airtm, ChatGPT, DeepL, etc…). Pourquoi ne pas laisser l’utilisateur importer ses propres images ?

Solid

My go-to 2FA. Syncs to my other devices.

Ganz OK, aber …

Ansich eine Super App, aber ein Feature fehlt, dass ich nicht nachvollziehen kann. Ich nutze einen Passwortmanager. Dieser wird mit Biometrie entsperrt. Um die sicherheit zu erhöhen habe ich für einige Dienste 2FA, ebenfalls als Handy-App. Diesen möchte ich natürlich auf eine andere weise entsperren als meinen Passwortmanager. Bei Proton geht aber nur Biometrie oder eben nichts. Keine PIN kein Passwort. Dass kann doch nicht das Problem sein eine Passwortabfrage zu Implementieren. Ohne, ist diese App nur für Leute ohne Passwortmanager auf dem Handy oder Leite die den Passwortmanager mit was anderem entsperren als Biometrie.

Schade eigentlich, sobald eine Umfangreichere App-Sperre integriert wird wechsle ich direkt!

Melhor 2FA

Uso a meses e recomendo, nunca tive nenhum problema!

I was too optimistic

I wish that the Proton Authenticator let you independently set a pin to the app separate to the passcode for your device if you are not using biometrics like you can with the desktop version. I don’t want to use biometrics on my devices. Ever! Nowhere was this behaviour discussed before I started using the app. I did not expect for it to be a case of use biometrics or be locked to your passcode. Disappointing. I do not appreciate the security risk Proton Authenticator has put me under. Passcodes can be overseen or otherwise stolen when used frequently from the plethora of security cameras and the ethics of those behind those cameras. Add the ability to create a custom pin/password so that my codes are more secure, please.

The other missing customisation that I find with Proton Authenticator is that there is no way to customise the icons for the tokens/accounts. Any change to the title changes the icon into a generic letter that doesn’t stand out. If you have multiple accounts from the same company it becomes impossible to tell them apart. If you could add your own icon you could then group the accounts by client or in a way that makes sense. Right now it is very difficult to do that. To the actual authenticator. It does what you would expect. It is nice that you can see the code coming up next so you can start to type that in if there isn’t much time left on the current code. But that is something I think should be standard. I want to see you do better.
