I cannot say that this will not happen, however, I have not heard that this ever happened…at the end you need to decide what is more important, no google at all, or some google depended and bought apps with the chance you will be blocked by google one day. you can hardly have all together, or I would say you might not be ready to live without google and maybe it would make more sense to you, to just reduce Google as mus as possible on FPOS or wait for Lineage OS, where you can install minimal Google Apps.

I’ve used a “burner” google account with Aurora Store for years now, never had any problems. I don’t use payed apps with it though, loosing it wouldn’t hurt me much.
Generally I’d classify this as a “grey area”, while you’re not supposed to use other Google Play clients, I can’t remember anyone getting blocked…

I have been using my Google Account with Aurora Store in combination with paid apps for almost two years now without any problems. I know several other LineageOS/iodéOS users with the same setup who also have no problems with blocked accounts

Sounds good! I’ve got iodéOS on my A5 and I like it.
A view additional questions.
Are there updates available?
Maybe from today. 
I didn’t get updates for my A5.
Did somebody know a good calendar?
Especially with swipe left-right for yearly-monthly-weekly-daily view and up-down for next year-month-week-day.
Many thanks
Updates: sees above
Calendar: Etar or simple calendar

On a correctly signed image, you can adb sideload same-signed updates via the recovery or via update_engine while the system is running.
When locked direct fastboot flashing is the only thing blocked.

That’s possible with iode on FP4.
It is “verified boot” and correctly signed.
@Iakhou
FYI
For everyone : all OTAs are now uploaded, except mi9 which is not finished yet.
So, you should find it now via updater.
Update 05.04.2022
iodé will release a new version for FP4 very soon with (a lot of) changes and security improvements
signed avb_custom_key instead of built-in googles test-key to increase security
it will not be available via OTA updater. Must be installed from scratch, unlocked bootloader and manual installation of avb key
means also, a factory reset is necessary.
Next version will then be available via OTA.
after long discussion and research, they took the decission to go that way. it’s nearly a complete change-over
But I don’t see this as a big annoyance, since we are still in the beta phase. That can and may happen.
I thought it was already the first stable version out:
How can I identify which version is still beta and which is already stable? 
Depends in the updater you are using
For betas a special updater is needed
Does it mean I can flash fastboot flash avb_custom_key after flashing the recovery and can flash, after factory reset, the iodéOS rom?
correct.
this guides you:
- remove SIM card and check that akku has at least 50%
- eneable USB Debugging and “Allow unlock OEM” in Developer Options
- check if adb is working and device is recognized correctly => adb devices => ACK USB debugging on phone-screen. check box: always trust
- adb reboot bootloader
- check if fastboot is working and device is recognized correctly => fastboot devices
- fastboot flashing unlock => Acknowledge unlocking on phone (VOLUME UP + POWER) Device is doing a factory reset and reboots to system
- start again in bootloader => switch phone off. pull out USB cable. press Volume (-) and put in USB cable in. Keep Volume (-) pressed. Phone should start in bootloader. (¹)
- check if fastboot is working and device is recognized correctly => fastboot devices
- fastboot flash recovery_a iode-2.4-20220405-FP4-recovery.img
- fastboot flash recovery_b iode-2.4-20220405-FP4-recovery.img
- fastboot erase avb_custom_key
- fastboot flash avb_custom_key avb_custom_key-FP4.bin
- press VOLUME UP until see message reboot in recovery. Then POWER
- From recovery => Factory reset => Format Data/factory reset
- From recovery => Apply update => Apply from ADB => adb sideload iode-2.4-20220405-FP4.zip
- back to bootloader mode. From recovery => Advanced => reboot to bootloader
- check if bootloader unlock ability is possible => fastboot flashing get_unlock_ability → (bootloader) get_unlock_ability: 1 ==> if you get 1 then follow with step 17) otherwise do not lock bootloader (can brick your phone) and follow with step 18)
- fastboot flashing lock
- reboot system. First should see a Lineage screen doing a wipe. After a second (automatic) boot you should see the yellow boot screen and then the iode bootscreen.
- start setup wizard
(¹) From FP Support Page:
Alternatively, you can disconnect the USB cable, turn off your Fairphone, then connect the cable and hold the volume down button. After a few seconds, you’ll see the fastboot mode

Many thanks for the detailed manual!
I’ll try when I got my device.
In case if something went wrong, how can I get back to the official FP4 rom?
honest? Not at all!
Coming from all custom ROMs I have only heard of problems.
from iode back did not work for all.
The problem lies in the signing keys and that FP uses test keys. IMHO
If this is too risky for you, then better don’t do it.

IodéOS looks very good and is very fast on my A5. I would love to keep it. But a last questions.
Can I flash other custom rom’s with this signed key?
Will I get updates for iodéOS for the next 5 years?
Many many thanks

Am I God ?
I am sorry, I don’t get it. Is 2.4 now out in the open or still beta? I am on 2.3 and don’t know what to do now? Thanks
