## What is 4Login/Pass Manager and Login?

4Login comes packed with a variety of convenient features for logging in.
Just remember one secret “pattern,” and you can use it for all your logins.

■ Security
・Your personal  information is encrypted and backed up on our servers.
・Because it is encrypted, even the operator (Passlogy) cannot view it.
・Even if your device is lost or damaged, you can restore your account as long as you remember your “pattern.”

■ Password Manager
・You can automatically generate a random password by selecting the character types and length.
・You can also choose a password based on Japanese hiragana converted into the Latin alphabet (e.g., “ka”, “shi”, …).
・Passwords are displayed on a 5×5 grid (“pattern”), so they remain unreadable even if someone sees your screen.
・Up to five password change history entries are retained.

■Auto-generate PINs for Your National ID Card
・Automatically generates the two (*) PINs required when you receive your national ID card.
・Meets the required rules for both PINs (character types and length).
・PINs are displayed on a 5×5 grid (“pattern”) like a cipher table, so they remain unreadable even if someone sees your screen.
・You can also register and manage existing PINs.
* Some countries define multiple PIN types. This feature covers the two commonly required ones: a 4-digit numeric PIN and a 6–16 character alphanumeric PIN.

■Two-Factor Authentication (2FA)
・You can add a one-time password (OTP) for 2FA by scanning a QR code. Manual entry is also supported.
・OTPs are displayed on a 5×5 grid (“pattern”) like a cipher table, so they remain unreadable even if someone sees your screen.
・You can also switch to the standard display mode.

■4Login Integrated Login
・Access advanced registration and sign-in features for software and websites integrated with 4Login (*).
・Register without creating a user ID or password.
・Sign in easily without entering a user ID or password.
・Start sign-in by scanning a QR code displayed on your PC screen with your smartphone.

### 1/5 — ver5.0.1にアップデートは注意

*2025-04-15, version 5.0.1*

ver5.0.1にアップデートした途端画面が真っ白になり何も表示してされなくなった。iPhone16ProMAX iOS18.4

### 5/5 — 使いやすい。

*2021-10-09, version 3.2.0*

パスワードの備忘録として必要十分な機能を備えている。他人が見てもわからない表示方式は、とても上手くできているし、安心感がある。電車内などでは重宝する。この方式だと、ひらがなの方が読みやすいのは確かだが、まだ使ってはいない。

### 4/5 — 閲覧用で使ってます。

*2018-07-11, version 2.5.0*

PCなどでログインする時に閲覧で使ってます。
他の人がパッと見てもわからないので便利です。
サイトなども記載してないので多分、他の人が見てもわからないと思う。

クラウド上にデータが置かれてるのがちょっとどうかと思いますが、それを差し引いても思った使え方が出来てます。

### 4/5 — 欲しい機能

*2017-11-24, version 2.3.3*

ウィジェットからパスワードなどをコピー出来るといいなあなんて

### 4/5 — 開発を進めればもっと素晴らしくなる

*2017-10-08, version 2.3.2*

passMからの試しで使ってみた感想です。
開発の余地はあり、素晴らしく良くなると思われる可能性は秘めている。人前で開けるのが大きな特徴。改良があればもっと良くなりそうな点は以下の通り。
一つ目は4つの位置で記録できるのは8文字までそれ以上溢れてしまったも文字は別の枠に記録される。その部分が見えてしまうのはパスコードを半分ぐらい公開しているのと同じなので安全性に欠ける。
iPadを持っている人もたくさんいるのででiPadとの連携がされてないので、iCloudと連携して管理ができるようなら素晴らしい。自社サーバに登録されるのはパスワードを一企業で監視されているようで気持ち悪い。

### 5/5 — ユニーク！

*2017-05-26, version 2.1.2*

パスワード管理アプリ色々試してみたけどこれすごいかわった仕組みだけど秀逸！

### 1/5 — 使えません

*2016-05-07, version 1.9.3*

斬新で面白いと思ったけど、メアド登録したら落ちます。
全く使えませんので早急に直してください。

### 5/5 — 愛用しています

*2016-03-06, version 1.9.3*

ワンパターンのpwを使い回すことがなくなりました。
このアプリを使っているiPhoneでは、pwを入力するアプリを同時に立ち上げると入力が大変ですけど、しようがないと思ってます。

### 2/5 — 残念

*2015-09-27, version 1.7.5*

編集しようとすると落ちます。
ちゃんと使えれば便利そうなアプリなのに残念です。
