### 5/5 — Просто и со вкусом

*2026-04-28*

Бомба приложение

**Developer response:** Спасибо, что пользуетесь и оценили!

### 5/5 — Самый удобный аутентификатор

*2024-06-04*

Прочитал статью на vc.ru, понравился подход автора к вопросу генерации кодов и хранения токенов. Поскольку однажды лишился всех ключей при обновлении Гугл аутентификатора, к нему больше не вернусь.

**Developer response:** Спасибо!

### 5/5 — Прощай Google Authenticator

*2023-07-22*

Простое и понятное приложение. Умеет добавлять аккаунты из скринов с кодами.

**Developer response:** Не забывайте удалять такие скрины☝️

### 5/5 — Отлично!

*2023-07-18*

И правда ничего лишнего

**Developer response:** А может всё-таки добавить папки, таб бар и рекламу?🤔

### 5/5 — Отличное приложение
